TYPO3 needs to support the Semantic Web in the core / RDFA / Web 3.0
0%
Description
I came across a video about Tim Berners Lee on the Semantic Web [1].
After that I jumped to an Introduction video [2] and then to an RDFa video [3]. After that I found this video showing RDFa in Drupal [4].
Drupal is raising thousands of dollars to integrate RDF semantics into the core [5]: The RDF code sprint will focus on Drupal core and aim at integrating RDF semantics in it.
1. Extend Fields API to integrate RDF mappings for each field instance. The semantics of a field can differ from a bundle to another. This can be stored either in the existing settings property or by adding a rdf_mappings property to the Field Instance objects.
2. Modify the Fields UI (contrib) to allow RDF mappings editing.
3. Define the appropriate mappings for the core modules, based on the RDF core mapping proposal.
4. Patch core modules with the mappings defined above.
5. Export these mappings in RDFa via the theme layer and keep it as generic as possible in order to ease the work of the themers.
6. Write tests for RDF in core.
7. Identify other non-fieldable entities in core which could benefit from being RDF-ized, and see how to annotate them. Comment is one example. Terms also, though they might become fieldable.
8. RSS 1 (RDF) in core. Arto volunteered to get started with that.
That's all well and good. More semantics on the web is good for all of us.
Google announced support for RDFa [6] data in may [7] an Yahoo has been indexing it for over a year already.
Benni wrote his diploma thesis on the Semantic Web.
What's the status of Web 3.0 and the TYPO3 core?

A new doctype needs to be added:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">
The file typo3/sysext/cms/tslib/class.tslib_pagegen.php must be changed: renderContentWithHeader() (line 303)
To support this kind of html tag:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#"
xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
xmlns:cc="http://creativecommons.org/ns#"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:foaf="http://xmlns.com/foaf/0.1/">
Or even more elaborate ones.

I totally agree that TYPO3 needs to support Semantic Web technologies, like tagging the content with RDFa. There is a project on forge that covers the whole topic:
http://forge.typo3.org/projects/show/extension-scotty
Adding xmlns is already possible. Just add this to your TS setup
config.htmlTag_setParams (
xmlns="http://www.w3.org/1999/xhtml"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:dcterm="http://purl.org/dc/terms/"
xmlns:ctag="http://commontag.org/ns#"
xmlns:c="http://s.opencalais.com/1/pred/"
xmlns:v="http://rdf.data-vocabulary.org/#"
xmlns:foaf="http://xmlns.com/foaf/0.1/"
xmlns:sioc="http://rdfs.org/sioc/ns#"
xmlns:sioctypes="http://rdfs.org/sioc/types#"
xmlns:fb="http://developers.facebook.com/schema/"
xmlns:og="http://opengraphprotocol.org/schema/"
)
Adding RDFa is possible via:
tt_content.text.10.innerWrap = <span property="dc:title">|</span>
This is of course a bit too low level. A more sophisticated option would be something like:
config.xlmns.dc = http://purl.org/dc/elements/1.1/
and
tt_content.text.rdf_property.1 = dc:title
tt_address.name.rdf_property.1 = foaf:name

I addition, you have to alter the DOCTYPE to
config.doctype = <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">
Then you have RDFa support in TYPO3. Anyway, there is a lot more to do in order to fulfill the vision of Semantic Web ;-)

Addtionally you could vote for #24043 in the core list to have a TYPO3_DB representation of 3-way-relations in the core.
This will give us the option to connect records based on a triple as well.

I have added a more specific feature wish to be able to add the DOCTYPE and the namespaces more easily.
