From martin.hepp at ebusiness-unibw.org Mon May 3 10:38:04 2010 From: martin.hepp at ebusiness-unibw.org (Martin Hepp (UniBW)) Date: Mon, 03 May 2010 10:38:04 +0200 Subject: [goodrelations] GoodRelations vs. Google RDFa vs. Open Graph vs. hProduct/hListing: Using GoodRelations in 10 Triples Message-ID: <4BDE8B6C.3040402@ebusiness-unibw.org> Dear all: Some people think that the GoodRelations ontology for e-commerce (http://purl.org/goodrelations/) is powerful, but complex. I think it is important for everybody in the community to know that GoodRelations can be as simple (or simpler) than any more lightweight approach for product markup, as long as you compare the same level of granularity. Below, please find an example of offering a car for sales in just ten (!) triples. Of course, you can do more with GoodRelations than just encoding a price and carrying the semantics of the product itself in a string. The important message in here is that simple chunks of data are as simple in GoodRelations as they are in hProduct/hListing microformats, Google's RDFa vocabulary, or the Open Graph product markup. The key difference is that GoodRelations has a much more extensible and, in my biased ;-) judgement: cleaner, conceptual model so that IF you have more granular data available, THEN you can expose it, and make your products more findable on the Web. For example, GoodRelations distinguishes between products and product models / datasheets. That allows for powerful linking between individual items and rich technical specifications from the manufacturer's page. The Open Graph approach seems to use a plain "topic" semantics, which mixes items, datasheets, and offers. Please keep that in mind and spread the word. Here is the markup.

In short, the simplicity of the other products can be had by using a subset of GoodRelations so there is nothing lost. There is much gained because it is extensible. IDEA: create documentation and tools for one or more simple subsets of GR, analogous to OWL-Lite, OWL-DL, and OWL-Full.

GoodRelations is available in English only, because a high-quality translation into other languages will be too costly, and a bad one will do more harm than good. The main problem is that natural languages have frequently no exact translations for very precise technical terms, since words are often biased by context etc. Personally, I do not think that translating GoodRelations into any other language than Chinese should be priority issue, because many relevant technical documentations are available in English only. I do see a need for good tutorials / examples of using GoodRelations in other natural languages. For example, I would be very happy (and explicitly grant any necessary rights) if volunteers will translate the Quickstart Guide at http://www.ebusiness-unibw.org/wiki/GoodRelationsQuickstart If you do so, please send me the link. As for products and services ontologies related to GoodRelations: - eClassOWL 5.1.4 is available in English only. In theory, we could produce versions in German and French, but 5.1.4 is a research prototype only, and licensing issues prevent us from offering translations. - We are evaluating the chances for eClass 6.x, i.e. proper transcripts from the new eClass 6.x family. That will support multiple languages, but it will likely require that you become a member of eClass e.V. to get access to translations. - freeClass, an ontology for the construction and building materials industry, is available in English, German, Czech, Italian, Romanian, Slovenian, Hungarian, and Polish. http://www.freeclass.eu/freeclass_v1.html Best wishes Martin Hepp On 01.02.10 18:20, Steven Forth wrote: > Hi Martin > > I hope you can take this as an opportunity to share some thoughts on best > practices in using ontologies across languages.
