Hi, My question is not directly connected to coding but I suppose there are some library geeks, interested in semantic web at this list. During the last years I have crafted (or I am still crafting) several ontologies to describe library related information in RDF. I try hard not to reinvent wheels but to connect to existing ontologies as much as possible. I also try to keep it simple (such as Dublin Core) by creating multiple small ontologies instead of one large library-ontology. For instance I created the general Simple Service Status Ontology (SSSO) to express the state of a service, such as lending a book (e.g. reserved, provided for pickup, on loan...), but also suitable for other services: http://purl.org/ontology/ssso Revisiting the ontology for Document Availability Information Ontology (DAIA) I thought about moving the list of library services to a small ontology of its own. Do you know of any more-or-less format lists, classifications etc. of library services? Is anyone else interested in an ontology of library services? I also asked this at StackExchange, you can answer there or here: http://libraries.stackexchange.com/questions/1403/what-basic-services-are-typically-provided-by-a-library Cheers, Jakob -- Jakob Voß <[log in to unmask]>, skype: nichtich Verbundzentrale des GBV (VZG) / Common Library Network Platz der Goettinger Sieben 1, 37073 Göttingen, Germany +49 (0)551 39-10242, http://www.gbv.de
