Welcome to the Semantic Web group in Drupal. This group was started at DrupalCon Barcelona 2007 and includes discussions on how to integrate the Semantic Web technologies into Drupal and list the various effort of the community towards enabling RDF in Drupal. Drupal 7 comes with native RDFa support in core. If you want extra RDF capabilities such as other serialization formats and SPARQL support, checkout the RDF Extensions, SPARQL and SPARQL Views contributed projects. If you need support or have found a bug in one of the fore mentioned projects, please file a ticket in their issue tracker (block on the right on each project page).
This news came a few days ago... Google is officially supporting the Good Relations (e-commerce) ontology as a source for Rich Snippets.
This means that once we have a good mapping for it in Drupal Commerce, sites that use Drupal for commerce will be at a distinct advantage. Yahoo research showed that click through rates for rich snippety search results were 15% higher, and other research has shown up to 30% higher.Read more
before I start with RDF, one question:
I'm searching a way to use short teasers and images of wikipedia articles on my website. I would like to have a small block, where people get a short information around the topic sailing. About different sailing boats, about sails.....
I would like to fetch the image url, and the first maybe 300 words of the article.
Am I right to start with RDF for this or should I use another way?
This wiki page is aimed at promoting a community consensus on an API for providing tag suggestions. Please join the discussion and help move this initiative forward.Read more

Whenever I try to import and external RDF library, I get this error:
* warning: Invalid argument supplied for foreach() in /home2/future/public_html/drupal/sites/all/modules/evoc/evoc.module on line 199. * warning: Invalid argument supplied for foreach() in /home2/future/public_html/drupal/sites/all/modules/evoc/evoc.module on line 199.
Then it tells me the namespace has been created.
Should I worry about this? What does it mean?

Please forgive the trivial nature of this question. I've been doing some background reading but not quite sure exactly where to begin.
I have a currently functioning Drupal 6 site. It works great with Views, CCK, and a few other modules. I want to add RDFa tags so content on my site can be found (and linked) from semantic web search engines. It seems like I would need to add three modules:

This really is not much of a deceleration.
The New York Times now uses Open Graph as a doc type. http://opengraphprotocol.org/schema/
I can't imagine getting editors of an online newspaper to submit this much data as outlined in the New York Times Annotated Corpus Overview. http://www.ldc.upenn.edu/Catalog/docs/LDC2008T19/new_york_times_annotate...Read more
Today at DrupalCon Copenhagen, we've had the biggest gathering of RDF enthusiasts at the two Birds of a Feather we had during the day. I don't have the exact number but I think we had about 40 people combined. The main RDF session on Thursday was a big hit as well and lots of newbies who never heard of RDFa until it was put into Drupal 7 joined us.Read more
A couple of weeks ago we launched Modulecraft an awareness & fund-raising project that aims to rally Drupal professionals around a shared effort to create the ultimate toolset for Drupal business. The first fundraising round has as goal the development of a documentation distribution for Drupal that uses a similar approach as the localization server and that enables a distributed/federated documentation architecture for the Drupal project. As a Drupal user you'll be able to get a set of documentation from the drupal.org docs server imported into your own site. You will than be able to edit it and build subsets of the documentation for your own projects. You'll also be able to submit topics that were edited or created by you on your own infrastructure and add them as suggestions to the Drupal documentation server.
The following is a first proposal for the specification of the Documentation system we want to build as part of the modulecraft project. It is by no means complete, and it strongly needs your feedback. This is our first encounter with DITA and our ideas should really be proof checked by technical writers that have extensive experience using DITA. It also contains some proposes a somewhat exotic usage of RDFa, feedback is also very much needed here. In the coming days I'll be adding new sections to the specification here. This is a wiki so be bold! You can add comments either here or at the original posts on the Pronovix blog. I'll be incorporating feedback into this wiki.Read more
While plugging away at the documentation issue queue I noticed that the RDF documentation (http://drupal.org/handbook/modules/rdf) hasn't been touched for a couple of years so I'm wondering if it needs to be updated in any way for Drupal 7.
I don't know anything about RDF myself, so if someone who's up to speed could look at this it would be really appreciated.
Anyone can edit the Drupal handbooks if they're logged in.
Obviously, the title was created was designed to elicit discussion ... but I am seriously interested in the prospects for unintended consequences of D7's default use of RDF. D7 will be a great leap forward, and I'm genuinely excited about the prospects of D7's adoption of RDFa. Upon further reflection, I'm wondering if D7's embrace might actually make it easier for users to be tracked by organizations like Recorded Future. I understand, that today's default settings can be "undone" ... but it is the default that has me most concerned ... precisely because it is the novice end user who isn't particularly savvy that will be put at most risk ... and is unlikely to even know what is going on "under the hood" ... I know, I know ... probably an exaggerated concern, but I thought I'd throw it out there and see if anyone might want to comment.Read more
I am publishing a web site called ThinkBanQ which is being developed by Mediacurrent, a local Drupal shop here in Atlanta. ThinkBanQ is primarily a forum for innovators invested in three major sectors. It employs many familiar social media tools designed to engage users and encourage greater participation as an open-sourced and self-determining community. Most significantly, this participation is semantically rendered, then valuated according to its contextual significance within the community. I like to think of it as “Facebook as if it mattered” or “LinkedIn on steroids.”Read more
I was wondering if anyone had any comments on the http://www.vivoweb.org project and it's relationship ship to Drupal. VIVO in a nutshell, is a web application provides a semantic database that can be searched that contains information about scientists, their research interests, affiliations, publications, grants, etc. VIVO is in deployment at several universities and is being expanded through a $12.2m stimulus grant from the National Center for Research Resources (NCRR) of the National Institutes of Health (NIH). see more at http://www.vivoweb.org/about/faq/about-projectRead more

We need to import arbritary catalogues (spreadsheets) into RDFable Drupal nodes.
We suggest the following as a way forward: before implementing this, we want to see if this would be useful to the broader Drupal RDF community, and whether it is compatible with other existing proposals:
Option 1: Dynamically create content types
For each import format dynamically create a node type that matches the field structure. Provide an RDF mapping for the created node type to enable the imported items to be tagged up with RDF.
Option 2: Define a generic content type for imports
Spreadsheets are imported into two node types. The 'header' includes the spreadsheet file and information about it's structure. A second content type is used to import each row. A row is a list of attributes taken from the column data for that row.
We also need to consider round-tripping issues, as follows:Read more
For those who missed DrupalCon San Francisco and are interested in learning more about the semantic web capabilities of Drupal 7, there will be a webcast happening on Friday at 11am PDT.
