type="cite">my concern however is that the semantic is dropped when
you get to what exactly you sell. I mean you do allow certain
predefined categories but then the description of what you actually
sell is left to the text. <br>
<br>
It would be cool to allow e.g. links to dbpedia for the kind of things
you sell. I am afraid as it is you get very very close to a great
enabling thing but might be stopping a step shorter? what do you think?<br>
<br>

This is just a constraint of the tool, not of the GoodRelations
ontology. The tool should be useable by any SME in teh world in five
minutes. This prohibits complexity (I am not sure how many hotels
owners in Canada know dbPedia at this point in time...).<br>
<br>
In GoodRelations, you have at least three options for describing WHAT
you are selling:<br>
<br>
a) Use an existing, fully-fledged products or services ontology (e.g.
eClassOWL). Many such ontologies are available or close to an official
release.<br>
eClassOWL allows a much more fine grained description of the item, e.g.
by ranges on properties etc.<br>
See <br>
<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://www.heppnetz.de/projects/goodrelations/primer/">http://www.heppnetz.de/projects/goodrelations/primer/</a>
<br>
<br>
and<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://www.heppnetz.de/projects/goodrelations/primer/#3.4_Step_2:_Products_and_Offerings">http://www.heppnetz.de/projects/goodrelations/primer/#3.4_Step_2:_Products_and_Offerings</a><br>
<br>
for details.<br>
<br>
b) Turn an proprietary structure (e.g. a large merchant's catalog
structure) into a proprietary ontology for products and services and
describe your items by references to that structure.<br>
This approach is (partly) described in <br>
<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://www.heppnetz.de/projects/goodrelations/documentation/vocabulary-dev">http://www.heppnetz.de/projects/goodrelations/documentation/vocabulary-dev</a><br>
<br>
The advantage is that you don't put a lot of burden on the publisher to
lift his/her data. Alignments with other structures can then be
established incrementally, elsewhere, and by someone else.<br>
<br>
c) Describe the item lexically only. <br>
Example:<br>
default:SonyCellPhoneModel_s1234<br>
a gr:ProductOrServiceModel ;<br>
rdfs:comment "Sony cell phone model s1234, water-proof,
shock-resistant"^^xsd:string ;<br>
rdfs:seeAlso <a moz-do-not-send="true"
class="moz-txt-link-rfc2396E"
href="http://www.sony.com/cellphones/s1234/"><http://www.sony.com/cellphones/s1234/></a>
;<br>
<br>
In this case, you formally know only that what is being sold is a
ProductOrServiceModel (or gr:ActualProductOrService or
gr:ProductOrServicesSomeInstancesPlaceholder), and that it is described
by a string that contains
certain words. <br>
<br>
But that may already be quite useful for queries - you can search for
something that is a product and whose textual description contains the
word "phone". And you have access to all commercial properties in a
machine-readable way.<br>
<br>
I assume that we can eventually get a really huge data cloud of product
and offering data on the Web pretty soon.<br>
<br>
Once that is done, we can start using all kinds of semantic
technologies to establish links and alignments between the variants a),
b), and c).<br>
<br>
Recipes and more developer information is also available in the Wiki at<br>

all:<br>
<br>
We are proud to announce the release of the GoodRelations Annotator, a
form-based tool that will help any business in the world to create a
description of its offerings suitable for the Web of Data,<br>
and that in less than 5 minutes.<br>
<br>
The tool is available at<br>
<br>
<a moz-do-not-send="true"
href="http://www.ebusiness-unibw.org/tools/goodrelations-annotator/"
target="_blank">http://www.ebusiness-unibw.org/tools/goodrelations-annotator/</a><br>
<br>
It creates a straightforward yet complete description of the key
aspects of a typical business using the GoodRelations vocabulary and
current Semantic Web standards.<br>
<br>
The resulting RDF/XML file can be either directly published on the
company's Web site or used as a skeleton for developing a more
fine-grained description with price information etc.<br>
<br>
The work on the tool has been funded by the Oesterreichische
Forschungsfoerderungsgesellschaft GmbH (FFG) and the Austrian
Bundesministerium fuer Verkehr, Innovation und Technologie (BMVIT)
under the myOntology project in the FIT-IT "Semantic Systems" program
(contract number 812515).<br>
<br>
Please help spread the word.<br>
<br>
Best wishes<br>
