GoodRelations - The Web Vocabulary for E-Commerce

This is the archive of the goodrelations dicussion list

GoodRelations is a standardized vocabulary for product, price, and company data that can (1) be embedded into existing static and dynamic Web pages and that (2) can be processed by other computers. This increases the visibility of your products and services in the latest generation of search engines, recommender systems, and other novel applications.

[goodrelations] osCommmerce: Installing the GoodRelations extension on an existing store

Dear all,

if you are trying to install the GoodRelations extension for osCommerce 
on an existing instance, the following information from Alex Stolz may 
be  useful:

unfortunately, a listing of code replacements is currently not available
yet. But I can give you a work-around.

1. RDF/XML dump output:
The setup of the RDF/XML data output is a straightforward process, for a
modified store as well. You just have to proceed the same like explained
in the manual, because RDF/XML output is located in a separate folder
and doesn't change anything to the Web shop system (except the provision
of a link tag in the template header that points to the RDF/XML-file).
So setting up RDF/XML output for a modified osCommerce system should not
pose an issue.

2. RDFa attributes embedded in XHTML:
The more cumbersome task is when you consider publishing your products
with RDFa - which is currently better supported by Semantic Web search
engines like Yahoo SearchMonkey. Then you have to modify some code
fragments in the template. I propose using "diff" to see the
modifications between the Semantic Web-modified version of the template
and the original osCommerce template. When comparing the modified RDFa
folder in the Semantic Web extension against the original osCommerce
sources, diff reports differences that I added as txt-files to the
attachments. In there you can see the line numbers in the original that
were modified.

I hope this helps!
