CfP: 2nd Workshop on Social Aspects of the Web

Wikier — Wed, 12 Dec 2007 10:57:16 +0000

[Apologies if you receive this more than once]

================================================================================

2nd Workshop on Social Aspects of the Web
in conjunction with
11th International Conference on Business Information Systems (BIS 2008)

Innsbruck, Austria
May 5, 6 or 7, 2008

================================================================================

Deadline for submissions: January 12, 2008

================================================================================

In recent years, the Web has moved from a simple one-way communication channel
extending traditional media, to a complex "peer-to-peer" communication space
with a blurred author/audience distinction and new ways to create, share and
use knowledge in a social way.
This change of paradigm is currently profoundly transforming most areas of our
life: our interactions with other people, our relationships, ways of gathering
informations, ways of developing social norms, opinions, attitudes and even
legal aspects as well as ways of working and doing business.
That change also raises a strong need for theoretical, empirical and applied
studies related to how people may interact on the Web, how they actually do so
and what new possibilities and challenges are emerging in the social, business
and technology dimensions.

The goal of this workshop is to bring researchers and practitioners together to
explore the issues and challenges related to social aspects of the Web. We want
to facilitate discussion on topics including theoretical, empirical and applied
studies related to:

TOPICS OF INTEREST

* Users in the social Web
* User identity/identities on the Web
* Activity patterns
* Privacy / intimacy in the social Web

Gnizr - social bookmarking application exporting SIOC

CaptSolo — Wed, 12 Dec 2007 10:57:14 +0000

http://www.geospatialsemanticweb.com/2007/11/16/gnizr-open-source

" The gnizr design is heavily influenced by Web 2.0 and the Semantic
Web. It features a del.icio.us-like user interface for tagging and
bookmarking. Users can create tag relations using SKOS vocabularies
(broader, narrower, and related) and export their saved bookmarks in
RDF (in SIOC and Tag Ontology). Saved bookmarks can be viewed in
different mashup API (Google Maps, MIT SIMILE Timeline and Aduna
Clustermap). "

This can be interesting to the SIOC community too as its slides
mention "Standardized message format based on RDF" as one of the
things that are planned to do next.

Semantic Web ideas from the DrupalCon Barcelona 2007

CaptSolo — Wed, 12 Dec 2007 10:57:10 +0000

[1] is a webpage containing ideas about combining Drupal and Semantic
Web. An excerpt follows. Perhaps this is something the SIOC community
is interested to take part in.

" What Drupal already offers:
Relationship - need to contact dman and see if he plan to work
more on this topic. If that's the case, we need to join forces.
FOAF - not up to date (4.6), walkah plans to work on it in the next months
SIOC - not up to date (4.7)
Semantic Search - alpha in Drupal 5 - would be nice to have 1.0
release for Drupal 5/6/7 . 4 should not be supported since it doesn't
support PHP5 (maybe I'm wrong?) (- hendler) Everything Drupal needs is
there as a proof of concept, but needs API, cleanup, and better
community.

What Drupal needs: a centralized and easy way of storing RDF data to
an optimized storage. An RDF storage abstraction layer would allow to
use any RDF store:
- internal RDF store implemented into Drupal database (semantic search
has this via ARC)
- external RDF store such as Yars,Sesame, Jena, Virtuoso etc. for
better performance and scalability (semantic search has this with
Sesame and others - see quick UML diagram here.)"

Call for Proposals: BlogTalk 2008 - The 5th Int'l Conf. on Social Software - Cork, Ireland - 3-4 March 2008

Cloud — Wed, 12 Dec 2007 10:57:10 +0000

BlogTalk 2008

The 5th International Conference on Social Software
Cork, Ireland - 3-4 March 2008

http://blogtalk.net/

= Overview =

Following the international success of previous BlogTalk events in 2003,
2004, 2005 and 2006, the next BlogTalk - to be held in Cork, Ireland on
3-4 March 2008 - is continuing with its focus on social software, while
remaining committed to the diverse cultures, practices and tools of our
emerging networked society. The conference is designed to maintain a
sustainable dialog between developers, innovative academics and scholars
who study social software, practitioners and administrators in corporate
and educational settings, and other general members of the social
software community.

We invite you to submit a proposal for presentation at the BlogTalk 2008
conference. Possible areas include, but are not limited to:

* Forms and consequences of emerging social software practices
* Social software in enterprise and educational environments
* The political impact of social software
* Applications, prototypes, concepts and standards

= Participants and proposal categories =

Due to the interdisciplinary nature of the conference, audiences will
come from different fields of practice and will have different
professional backgrounds. We strongly encourage proposals to bridge
these cultural differences and to be understandable for all groups
alike. Along those lines, we will offer three different submission
categories:

* Academic
* Developer
* Practitioner

For academics, BlogTalk is an ideal conference for presenting and
exchanging research work from current and future social software
projects at an international level. For developers, the conference is a
great opportunity to fly ideas, visions and prototypes in front of a
distinguished audience of peers, to discuss, to link-up and to learn
(developers may choose to give a practical demonstration rather than a
formal presentation if they so wish). For practitioners, this is a venue
to discuss use cases for social software and to report on any results
you may have with like-minded individuals.

= Submitting your proposals =

Please upload your submission along with some personal information at
the http://www.easychair.org/blogtalk2008/ site. You will receive a
confirmation of the arrival of your submission within three working
days. The submission deadline is November 16th, 2007. The length of the
proposal should be between two and four pages. BlogTalk is a
peer-reviewed conference.

= Timeline and important dates =

Proposal submission deadline: November 16th, 2007

Notification of acceptance or rejection: December 7th, 2007

Paper version due: January 7th, 2008

Presentations and abstracts on website due: February 7th, 2008

(We will work hard to endow a fund for supporting travel costs. As soon
as we review all of the papers we will be able to announce more details.)

= Chairs =

* John Breslin
* Thomas N. Burg
* Tom Raftery
* Jan Schmidt

= Programme Committee =

* Stowe Boyd
* Dan Brickley
* Jyri Engeström
* Jen Golbeck
* Eugene Eric Kim
* Kevin Marks
* Peter Mika
* José Luis Orihuela
* Jeremy Ruston
* Paolo Valdemarin
* David Weinberger

Potluck: Semi-Ontology Alignment for Casual Users:
http://www.cs.vu.nl/~pmika/swc-2007/Potluck.pdf

"Potluck is a web user interface that lets casual users--those without
programming skills and data modeling expertise--merge and repurpose
heterogeneous Semantic Web data. It lets users merge, navigate,
visualize, and clean up data all at the same time, using direct visual
manipulation.
This iterative process of integrating the data while constructing
useful
visualizations is desirable when the user is unfamiliar with the data
at the beginning--
a common case--and wishes to get immediate value out of the data
without having to spend the overhead of completely and perfectly
integrating the data first"

sioc:reply_of in flat threads

Thomas Schandl — Tue, 13 Nov 2007 08:46:29 +0000

Hi!

I'm currently working on a SIOC exporter for vBulletin using Alex's
SIOC PHP API.
As vBulletin uses flat threads, I was thinking about the correct way
to use the sioc:has_reply and sioc:reply_of properties for posts.

The problem here is that we can't know for sure which post the author
of a follow-up post is replying to:
It could be a reply to the previous post in the thread, to the thread
starting post or even to multiple posts in the thread.
So how can we use the sioc:reply_of property for a post in a flat
thread - should it point to the immediately previous or the thread
starting post - or even all or none of previous posts? [1]

In a discussion [2] on #sioc irc channel it was proposed to use
sioc:Thread [3] to indicate that sioc:Posts are part of a discussion.
It was then suggested to either have
* each post marked as a reply to the first post or
* something like a linked list of posts using sioc:next_by_date and/or
sioc:previous_by_date
and maybe add a property like sioc:first_post to sioc:Thread so that a
query is able to find the first post of a thread (sioc:first_post
being a subproperty of sioc:container_of)

Then rules could be used to deduce more knowledge about the thread and
its reply structure later.

Any comments and suggestions are very welcomed.

Regards,
Thomas

[1] Ideally a web forum application would store the IDs of posts that
are quoted in a reply, but vBulletin doesn't do that in a useful way.

SIOC, IRC and events

Alexandre Passant — Sat, 03 Nov 2007 17:02:47 +0000

Hi all,

Having some thoughts this afternoon on how to represent a user
connecting / disconnecting channels on IRC, I thaught a sioc:Event
class might be useful.
More generally, it can help to represent subscription to
sioc:Containers, as IRC join / quit, RSS subscribing, starting
membership in a forum ...

This Event class could be defined in the SIOC core itself, but we may
also reuse (or subclass) existing Event classes from other ontologies
(I didn't look yet, but I think that iCal / music ontology Events may
fit there), and use
- sioc:has_creator
- sioc:has_container
- dcterms:created
- dc:description
to define event property and link it to associated Container / User

More specific event types could be then defined in SIOC core or in
external module, as, JoinEvent / QuitEvent and AwayEvent / BackEvent.
(And even some types specific to the container (as IRCJoinEvent), but
I'm afraid it will lead to a lot of event types, while the 4 first
ones should be enough to describe almost everything, combined with the
sioctypes module to define container type (IRC, Forum ...))

Eg:

a sioct:ChatChannel.

a sioc:JoinEvent ;
sioc:has_container ;
sioc:has_creator ;
dcterms:created "2006-11-03T12:05:00Z"^^xsd:dateTime .

a sioc:QuitEvent ;
sioc:has_container ;
sioc:has_creator ;
dc:description "Leaving" ;
dcterms:created "2006-11-03T12:10:00Z"^^xsd:dateTime .

Any comments ?

Best,

Alex.

RDFa support in SemRadar

Sergio Fernández — Mon, 08 Oct 2007 07:47:29 +0000

Hi,

as I already announced in RDFa mailing list [1], I've written a concept
test to detect RDFa in Firefox [2].

I think that could be interesting add RDFa support in SemRadar [3].
What's your opinion about it?

URIs in SIOC

Oskar — Mon, 27 Aug 2007 08:12:23 +0000

Hi,

first I have to apologize if this posting floods your inbox; there
seem to be problems with google groups and I keep getting error
messages about not being allowed to post here... Seems I lost control of
what gets posted and how often.

My question is about the use of URIs in SIOC:

In the few examples on your project homepage and in the sioc-files
floating around in the wild it seems that there is a common (and, as
far as this mailing list goes, undisputed) practice of using document-
URIs for non-document resources. sioc:user, for example, is almost
always identified as some HTML-document, same for sioc:site and,
sometimes, sioc:container/sioc:forum.

Is this by design? Is sioc:user something like a hidden
sioc:userHomepage, the way FOAF uses a workplaceHomepage rather than a
URI for the company I work at? If so, wouldn't this break the concept
of sioc:user being a sub-property of foaf:Account?

In other words: If I use a non-document URI for a sioc:user or a
sioc:forum (which a thought would be more elegant), do I break things
or is it just a matter of preference?

Thank you for your support,

Oskar

CfP: 2nd International ExpertFinder Workshop: FEWS2007 (Finding Experts on the Web with Semantics)

Cloud — Thu, 09 Aug 2007 12:24:55 +0000

Call for Papers

2nd International ExpertFinder Workshop:
FEWS2007 (Finding Experts on the Web with Semantics)
http://fews.semanticweb.org/

Busan, Korea, 12th November 2007

co-located with the 6th International Semantic Web Conference (ISWC
2007) and 2nd Asian Semantic Web Conference (ASWC 2007)
=============================================

ExpertFinder (http://rdfweb.org/topic/ExpertFinder) is an emerging
collaborative initiative with the aim of devising vocabulary, rule
extensions (for e.g. FOAF and SIOC) and best practices to annotate
personal home pages, as well as web pages of institutions, conferences,
publication indexes, etc. with adequate metadata to enable computer
agents to find experts on particular topics.

Following the 1st ExpertFinder workshop
(http://lsdis.cs.uga.edu/~aleman/efw2007) during the Knowledge Web NoE
general assembly in January 2007, the ExpertFinder initiative would like
to solicit research contributions from the wider Semantic Web expert
community.

ExpertFinder's goal is to enable a Web-scale infrastructure for the
creation, publication and use of experts' semantic descriptions to
support expert finding scenarios such as group management, disaster
response, recruitment, team building, problem solving and on-the-fly
consultation. Descriptions of such scenarios can be found at
http://rdfweb.org/topic/ExpertFinderUseCases. We welcome all submissions
which describe original research contributing to this goal.

Topics of Interest
==================

We welcome all research contributions that address one or more of the
following topics:
* Specification of vocabularies to describe experts
* Reuse of existing standards and taxonomies to describe experts
* Extraction of expert descriptions from legacy (meta)data
* Use of microformat data to locate experts
* International and cross-organisational heterogeneity issues in the
expert descriptions
* Algorithms for expert finding and recommendation (e.g., mining of
social networks)
* Expressivity extensions (in logics, rules) to support expert finding
processes
* Tools for the intuitive creation and maintenance of expert
descriptions and associated rules
* Web infrastructures for the publication and sharing of expert
descriptions (storage, access, querying, rule execution, coordination,
communication)
* Security, trust and privacy aspects of expert finding
* Scalability to the Web level
* Integrating expert finding research into legacy systems to support
industrial uptake

Event Information
=================

The workshop will take place during the 6th International Semantic Web
Conference (ISWC2007) and 2nd Asian Semantic Web Conference (ASWC2007)

For every accepted paper at least one of the authors must attend the
workshop and must register for the workshop and the main conference.

Submission Information
=================

We invite submissions of papers no longer than 14 pages (including
figures, references and appendices). Paper submissions must be formatted
in the style of the Springer Publications format for Lecture Notes in
Computer Science (LNCS). Guidelines and templates are available at
http://www.springer.de/comp/lncs/authors.html.

Papers need to be submitted electronically through the conference
submission site: https://cmt.research.microsoft.com/ISWC2007/. Papers
will be published in accompanying online proceedings (CEUR) as well as
in hardcopy which will be available to all workshop attendees.

Stats of SIOC-Dev - the list is growing (100+)

CaptSolo — Thu, 09 Aug 2007 12:24:54 +0000

Dear All,

July has arrived and it reminds of something we wanted to write about
earlier - SIOC-Dev list has grown to 100+ members. Thank you for your
interest in SIOC and we hope to have many interesting and useful
discussions here.

Actually, 100+ is old news.

Currenly there are 119 members who have created a total of 696
messages. 100th member of SIOC-Dev is Steve Cayzer [1] and some of
recent SIOC-Dev message authors joined just before that (e.g., Keith
Alexander and John Hoogstrate). If you joined just recently (maybe you
even know you're 119th? :), welcome to let yourself known and
introduce yourself.

[1] http://www.hpl.hp.com/personal/Steve_Cayzer/index.html

The most active thread of the recent month was: "Ontology suggestions
needed" [2], started by John Breslin with 8 messages in total, the
last by Alexandre Passant. Due to the way Google Groups shows messages
(by the date of the last reply) it falls within the archive of this
month even though was started a bit earlier.

If someone wants to do a more detailed analysis of SIOC-Dev stats and
dynamics that would be great. There sure is more that can be done -
highlighting the messages which you see as the most interesting, or
those which need to be followed up, etc... Please do your thing and
share with others. ;-D

The previous report of SIOC-Dev stats [3] raised a question by [GNU] -
where is the RDF version? If by this you mean something derived from
mailing list posts (e.g., a community of posters) then you will have
to create it. But as Sergio pointed out in another reply to [3] - all
the data needed (SIOC-Dev posts in SIOC RDF) are available at [4] and
the derived information can be acquired via a simple SPARQL query.

[4] http://swaml.berlios.de/demos/sioc-dev/

Of particular importance to SIOC-Dev is a post titled " ANN: New
documents - (1) SIOC Implementations list; (2) Relations w. other
ontologies; (3) Update to the SIOC Specification" [5]. It announces
the results of joint work of everyone here in coming up with a new and
solid SIOC specification and two other documents (they're well worth
exploring). Now it's time to build more applications that put SIOC
data to some good use! :)

[5] http://groups.google.com/group/sioc-dev/browse_thread/thread/cd2bccb43487c402

P.S. And soon, i hope, we will have some more news regarding the
documents mentioned in [5]. Stay tuned for more.

Fwd: [wiki-standards] Wiki Profile Vocabulary

CaptSolo — Thu, 09 Aug 2007 12:24:54 +0000

---------- Forwarded message ----------
From: Earle Martin

Subject: [wiki-standards] Wiki Profile Vocabulary
To: The discussion list for wiki standards

Hi all,

Thanks to everyone who attended Tuesday's IRC meeting
(http://wikiohana.net/cgi-bin/wiki.pl/IrcMeetingJuly2007) - it was
productive. For those who weren't there, I was inviting discussion on
a project I've been working on called the Wiki Profile Vocabulary,
which is essentially an RDF vocabulary for describing wikis and
aspects of wikis. (The idea was originally suggested by Ward; thanks.)
You can find the latest version at
http://wikirdf.org/vocabulary/profile/ . There's also an article I
wrote about what a "profile document" is and how to make one, at
http://wikirdf.org/docs/creating-wiki-profiles.html .

What I'm hoping that wiki authors will do is add support for producing
these profile documents to their wiki engines, complete with
autodiscovery tags in the sections of their HTML pages, in
order for robots and other mechanisms to find the information. In
theory, it would be possible to write code to automatically generate
sister site links from one wiki to another, just by entering the URI
of the other wiki.

Two main points were discussed:

The current version of the spec has a naive expectation that wiki URIs
are roughly of the form
http://example.com/scriptname?args=whatever;page=[page name here].
However some wiki engines use URIs of the form
http://example.com/scriptname/[page name here]/args. Chris Dent
suggested using URI Templates
(http://bitworking.org/projects/URI-Templates/) to define the form of
URIs, and this was generally agreed to be a good idea.

The other point was how to specify an autodiscovery method in page
HTML that points to a wiki's profile document. Suggestions were (note,
examples only; your engine's URI for producing a profile doesn't
matter):

A la Dublin Core (suggested by Reini Urban):
link="/wiki?action=profile">

A la FOAF (http://rdfweb.org/topic/Autodiscovery):

Hybrid:

href="/wiki?action=profile">

Hybrid, n3 version:

href="/wiki?action=profile&format=n3">

Also, the possibility of having a "standard location" like robots.txt
(http://www.robotstxt.org/) was mentioned, but was thought to be too
inflexible.

Out of all of these, I very much prefer the second, FOAF-style option,
because the profile is very much an example of metadata, and I'm not
too sure about how the "x.y" syntax works.

On the other hand, reading through the W3C specs, it is apparently
legal to have any QName (XML qualified name - see
http://www.w3.org/TR/xmlschema-2/#QName) as the value of a "link rel",
and a XML prefix can be used as long as it's been defined in an xmlns
attribute (http://www.w3.org/TR/xhtml2/mod-metaAttributes.html#adef_metaAttributes_rel).

So I guess it would be possible to do

href="/wiki?action=profile#Wiki">

...but that seems a little over the top.
is a
well-known style and shouldn't cause any problems.

Cheers,

Earle.

Multi-linguality in SIOC

CaptSolo — Thu, 09 Aug 2007 12:24:54 +0000

Hi All,

Multi-linguality in SIOC is something we need to think about. Summer
is a bit quieter season than usual on SIOC-Dev, but there's a lot to
do and I hope this message will raise us all to some constructive
discussion.

Immediate reasons that made me write this post:
- SSSW 2007 summer school, which I am at now. It brings together an
interesting and very multi-cultural groups of students, tutors and
organisers (and you realise English is not the only language in the
world);
- Stehanie Booth giving a talk today at Google about languages on the
Internet [1].

There are 2 main directions for multi-language support in SIOC:

1) Ontology

We can translate the ontology (labels and comments for all classes and
properties) into other languages, similarly as it's done with DOAP.
End-users could benefit from this, but mainly if they use generic RDF
browsers which make use of these labels and comments.

All the term comments and labels have xml:lang="en" (thanks for the
suggestion to add it!) and hence translations in other languages can
be simply added. All we need is those translations. :)

2) Data

Establish how to express multi-language content in SIOC RDF. This
should be entirely possible with the existing SIOC ontology, just need
to add a property (dc:lang) to specify what language a post/item is
in. This possibly has a larger impact than 1) but a question is how to
get those data? Do blog engines (say, WordPress or MovableType) always
know what language a post is in?

Of course, it depends on our requirements. If we find out that a
post/content can have multi-language content inside it (= there is >1
language per post) and we want to model these fragments, that may
require a somewhat more complex solution.

What do you think about it? What are the best approaches to solve
this, what are the challenges?

ANN: New documents - (1) SIOC Implementations list; (2) Relations w. other ontologies; (3) Update to the SIOC Specification

CaptSolo — Thu, 09 Aug 2007 12:24:53 +0000

Dear All,

New SIOC-related documents are here:

1) SIOC Ontology: Applications and Implementation Status

http://rdfs.org/sioc/applications/

Describes all the applications which use and implement SIOC, or are
related to this project. (Of course there can be more applications
which we are not aware of. If you know of any, please write.)

2) SIOC Ontology: Related Ontologies and RDF Vocabularies

http://rdfs.org/sioc/related/

Describes vocabularies / ontologies which are related to SIOC, along
with details on what these relations are and some examples.

---

Also published a new version of the SIOC specification:

3) SIOC Core Ontology Specification - 12 June 2007 - v1.26

http://rdfs.org/sioc/spec/

We went over the specification and improved it where possible - better
descriptions for terms, improved SIOC ontology figure and all other
things that could be made better. sioc:Service related properties
moved to a separate module.

Detailed term definitions in the specification now properly abbreviate
all the namespaces referenced, and also include rdfs:subClassOf and
rdfs:subPropertyOf relationships (a result of improvements to the
SpecGen4 script).

Renamed the main document to the "SIOC Core Ontology Specification" to
account for the fact that there are also "SIOC Types module" and "SIOC
Services module".

---

This feeds into the preparation work for the SIOC member submission,
which is now finished.

Thanks a lot to all who contributed. Special thanks to John Breslin
for co-ordination, to Axel Polleres and Alexandre Passant for creating
the intial versions of the related ontologies and the implementations
list documents respectively.

If you have any questions, ideas or comments please write to the list
or to the editors of these documents.

Thanks,
Uldis

ActiveRDF for Python ?

CaptSolo — Thu, 09 Aug 2007 12:24:53 +0000

Hi,

Is there a framework for Python which implements the ActiveRecord
model for RDF data, similar as ActiveRDF does for RoR ?

Apologies if this is a bit of offtopic. :)

P.S. Thanks for the SIOC Explorer [1], it is a great tool for
exploring SIOC data. Congratulations for the 2nd place at the
Scripting for the Semantic Web challenge!

Nice quote about SIOC

Cloud — Thu, 09 Aug 2007 12:24:50 +0000

"Unfortunately, MySpace, the most popular social networking service, which houses the biggest social network ever, makes its money by NON-distribution of that data. They sell eyeballs to advertisers, so distributed networking is inherently contrary to their business model.

An approach like what SIOC is aiming for, “Semantically Interlinking Online Communities,” is probably what will induce the big shift to Semantic Web practices. What is needed is users, so there will be a place for the next wave to take place."

Human Readable s

keith alexander — Mon, 23 Jul 2007 13:03:01 +0000

Hi all,

I notice that the rdfs:label of http://rdfs.org/sioc/ns#creator_of is just
'creator_of' which I don't think is very useful.

It makes it harder to build friendly looking public-facing RDF browser
applications.

I think it would be good to change sioc's labels to be actually human
readable (rather than human decipherable). So "Creator of" rather than
"creator_of"

It would also be good to add plural/singular labels as appropriate, using
Morten Frederikson's label vocabulary:
http://www.wasab.dk/morten/2004/03/label

What do you think?

ANN: int.ere.st is lauching!

sonagi.kim — Thu, 19 Jul 2007 08:47:28 +0000

Hi all,
I am happy to inform that http://int.ere.st is launching. The main
objective of int.ere.st is to demonstrate how Semantic Web and Web2.0
technologies can be combined to provide better metadata creating and
sharing support across online communities. With int.ere.st, you can
save, tag and bookmark your own as well as others' SCOT ontologies.
The tag meta search allows you to look for similar patterns of tagging
of persons with their interest based on tags. Various functionalities
are given as following:
- various tag search: and(&), or(space), co-occurrence(+), broader(>),
and narrower(<)
- User search
- Meta tagging
- Resource search
- Ontology bookmark
- Integrate tagged data across communities
- Share FOAF, SIOC, and SCOT ontologies
You can try it at http://int.ere.st
And you can get more detailed information about SCOT ontology in
http://scot-project.org
I will release a next version of the SCOT exporter as soon as
possible.

Best Regards,
haklae

Fwd: [RDFa application] MLE - mailing list archives explorer

Hi,

here is an interesting new application using SIOC, via RDFa mailing
list.

Asunto: [RDFa application] MLE - mailing list archives explorer
Fecha: Wed, 18 Jul 2007 09:01:16 +0200

Dear RDFa folks,

I'm delighted to announce the availability of MLE (pronounce: Melly)
[1]. MLE is the 'mailing list archives explorer', and basically
enhances (W3C) mailing list archives with SIOC metadata, deployed
with RDFa -as a result, SPARQL queries can be executed on top of it.

With MLE it is demonstrated, how existing data sources can be
enriched/augmented with RDF, to finally enter the Semantic Web.

Any feedback welcome!

Cheers,
Michael

BTW: I recently submitted MLE to the ISWC 2007 challenge [2].

ANN: UMBEL Subject Reference Project

mkbergman — Thu, 12 Jul 2007 21:26:42 +0000

Hi All,

You are cordially invited to comment or participate in the UMBEL
(Upper Mapping and Binding Exchange Layer) project. I think it will
be a very nice complement to SIOC.

UMBEL is a lightweight way to describe the subject(s) of Web content,
akin to the relationship "isAbout". It is meant to work universally
with HTML, tagging, microformats or other standard practices,
including various RDF schemas and more formal ontologies. Its
reference subject 'backbone' is derived from the intersection of
common subjects found on popularly used Web sites and other accepted
subject references.

UMBEL is very simple with few ambitions. It is merely a reference
'bag of subjects' to help relate Web data sets to one another.

UMBEL makes no presumptions to replace formal domain or upper
ontologies, has little or no inferential power, and makes no
assumptions about the means to describe or serialize the underlying
data. UMBEL is meant to work with data sets ranging from RSS and Atom
feeds to tagging, microformats, RDF, existing schema and other data
and metadata models. UMBEL's development is being backed by a number
of leading open data efforts and entities.

In addition to its core reference subjects, the UMBEL project will be
providing look up, query, registration, pinging, and related services.
The project is completely open under a community process with all
products available via Creative Commons licenses.

The initial project site is at http://www.umbel.org, including an
introduction (http://www.umbel.org/intro.xhtml) (the best place to
start!) and the draft project specification (http://www.umbel.org/
proposal.xhtml).

A mailing list you can monitor or join is at http://groups.google.com/group/umbel-ontology.

We welcome and invite your participation!

Best regards,

Mike Bergman

Tying identity information together?

dryburghl@gmail.com — Fri, 22 Jun 2007 14:17:34 +0000

Getting data from multiple sources is great but how in practice is the "digital identity" aspect handled; how do you know the user MrDoe on forum X is MrSmith on forum Y, and user MrJones on Drupal CMS system Z etc? I mean how can you tie these identities together? Ideas on a postcard welcome :)
