SIOC profile for 'sioc-project.org' A SIOC profile describes the structure and contents of a community site (e.g., weblog) in a machine processable form. For more information refer to the <a href="http://rdfs.org/sioc">SIOC project page</a> Contribution from UMU to SIOC Ontology These are the comments, questions and suggestions that have come up as a result of our analysis of the SIOC ontology. We have generated comments for a number of main concepts in the ontology. The following is a list of the concepts which received some comments from our side: ·Forum - It is declared that a forum will have a moderator or administrator, but how is this relation represented in the model? Does it come implicitly by a concrete role played by a subscriber of the forum? - The meaning of "scope_of" property is not quite clear. Does it mean that a forum is only visible to a fixed type of role? Or is it interesting to a specific type of role? Another possibility that we have thought of is that this property tries to represent the administration relation that we have mentioned in the previous point, but it seems a bit weird, because is a user who moderates a Forum, not a role. - A forum could be devoted to a certain group of users, but how is represented the relation among forums and groups of users, that is to say, how do you associate a group of user with a forum? It seems that neither a direct relation nor an indirect one model this fact. ·Post - "Content" and "description" properties have got the same semantic meaning; it seems that there is no difference between them. We have read in [1] that currently it is being considered the idea of inserting AtomOWL to represent the content of a post, which sounds to be a good choice. So we suppose that these two properties will be reduced to one of this AtomOWL type. ·User - As in Forum class, we can't see a relation that allows representing that a user is moderator of a forum or site, as is stated in the specification. That is to say, we miss a property that relates a user with the administrator role with a forum, and its inverse (a forum that is administrated by a user), like "subscriber_of" property does. ·Usergroup - Should "usergroups" have a role? It is not explicitly mentioned in the specifications, and there isn't any relation between this class and the "Role" class that could state this situation. For example, a group of users could be defined as banned users or as administrator of a site. Then, users could be added to these groups without the necessity of specifying their roles, as they could be inferred from the group where they belong to. ·About "topic" property We think that "topic" property should be modelled as a class and not as a property, since topic is a sufficiently important entity to having its own properties: category, description, keywords, impact factor, etc. [1] http://rdfs.org/node/128 Best Regards, Andrés Muñoz University of Murcia, Spain --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "SIOC-Dev" group.
