From martin.hepp at ebusiness-unibw.org Mon Apr 19 10:08:14 2010 From: martin.hepp at ebusiness-unibw.org (Martin Hepp (UniBW)) Date: Mon, 19 Apr 2010 10:08:14 +0200 Subject: [eclassowl] Preview: GoodRelations Service Update 2010-04-12 Message-ID: <4BCC0F6E.3010301@ebusiness-unibw.org> Dear all: We pretty much finalized a service update for GoodRelations, which mainly defines a few additional properties that are important for the rental and accommodation business. Also, we redesigned the language reference in HTML completely. Except for a few minor issues listed below, the update is fully backwards-compatible and should not break existing data or code. A preview is available at http://www.heppnetz.de/ontologies/goodrelations/20100412/v1.html http://www.heppnetz.de/ontologies/goodrelations/20100412/v1.owl An UML diagram highlighting the planned extensions is at http://bit.ly/cRTRE6 A change log is at http://bit.ly/dhXqY9 Please report any suggestions or feedback before Thursday, April 22, 2010. We plan to officially release the service update on Friday. Highlights: ========== - validity dates for opening hours - new gr:owns property for indicating the products that you own, which allows exposing ownership data for future recommender systems - availability intervals for offers, important for rental businesses - eligible contract durations and advance booking requirements - shipping and delivery charges can now be constrained to order volumes in terms or quantity or a monetary amount ("free shipping from 20 USD onwards..." - ordering relations for qualitative values, which may be useful e.g. for modeling garment sizes (XL>L>M>S) etc. Backward Compatibility: ====================== The only changes that may (but should not) affect existing data or code are the following: 1. We removed the rdfs:range statement for gr:legalName. It used to be xsd:string, but that prevented someone from indicating the natural language, since the language tag can only be attached to untyped RDF literals. 2. We changed the domain of gr:validFrom and gr:validThrough to the union of gr:Offering, gr:OpeningHoursSpecification, and gr:PriceSpecification instead of just gr:Offering and gr:UnitPriceSpecification. This allows specifying the validity interval of offers, opening hours, payment charge specifications, and delivery charge specifications. The rest are either fixed typos or additional language elements that are fully backwards compatible.

It defines classes for more than 30,000 product types and more than 5,000 properties for product features. Under the hood, eClassOWL is a non-trivial transformation of the eCl at ss standard [1]. eClassOWL complements the GoodRelations ontology [2] in the sense that - eClassOWL can be used to describe the product type and features, and - GoodRelations can be used to describe the offer and other commercial aspects. We just replaced the pretty dated documentation and primer Web page at http://www.heppnetz.de/projects/eclassowl/ so that it better explains the interplay with GoodRelations etc. and is based on the current state of Web engineering. The full theoretical background is described in [3] and [4]. Notes: ===== - eClassOWL 5.1.4 is based on eClass 5.1.4, while the latest version of eCl at ss is now 6.1. - We are discussing an official release of eClassOWL 6.x these days, but it may take a while. - Due to backward compatibility issues, eClassOWL 5.1.4 still uses hash URIs and is pretty large (in total > 60,000 classes, 30 - 70 MB file size depending on the format). As per the nature of hash URI-based ontologies, any application dereferencing a single element will always request the full file. This will change in any future release, but is a limitation of the current state. - Due to licensing issues, eClassOWL 5.1.4 is available freely for research purposes only. Commercial usages will require a bilateral agreement with eCl at ss e.V. Acknowledgments: =============== We would like to thank eClass e.V., in particular Friedhelm Hausmann and Thomas Einsporn, and Jos de Bruijn, doug foxvog, Axel Polleres, and Amit Sheth for their kind support and feedback over the seven years of the project. The work on eClassOWL was partly funded by Florida Gulf Cost University, by the European Commission under the project DIP (FP6 - 507483), and by the Trans IT Entwicklungs- und Transfercenter at the University of Innsbruck.
