Semantic Web
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).
Apache stanbol problem
Hi people,
can anybody give me advice? What is difference between D7 and Semantic CMS (D7 also) made by IKS projekt? (available at http://semantic-cms.info/). I took all modules from S-CMS and have instaled on my D7 site (Aloha editor, Apache stanbol). But when I enable Apache stanbol I can´t edit text and also make contet. Its imposible to save it. I can make changes and save it, his problem relates only to content.
Thanks...
Schema for News articles?
Hi everyone!
I'm building a newspaper website and am trying to use best practices with regards to metadata and semantic web.
To this end, I'm thinking it makes sense to use some sort of semantic web schema for articles. I've found two:
- Open Graph protocol -- http://ogp.me/ (Facebook-based)
- rNews -- http://dev.iptc.org/rNews (IPTC)
JSONP SPARQL module on d.o
Hi.
Just wanted to let you know that I just put up a small and simple new module (sandbox atm) that i would love to get some input on from the brave semantic soldiers in this group.
I still have some work planned on it to make it even more universal, but at the moment it supports most SPARQL endpoints out-of-the-box. It is a module to do content enrichment from SPARQL endpoints entirely client side (JSON with callback), so Drupal sites don't have to slow down while waiting for a response from external services.
Module request:Good Relations vocabulary for Drupal
Hi,
I would like to ask if the Good Relations vocabulary will be available for Drupal.
Also,can I use this vocabulary to a site that has products but it's not an e-commerce site?
Thanks
Schema.org for a social network
Hi,
I would like to create a social network of people and use the schema.org module/vocabulary.
According to the drupal tutorial http://drupal.org/node/1351214 it says to create a new content type for people.
"Go to Structure -> Content Types -> Add content-type and create a content type with the following name and description:
Person
Person that uses schema.org Person Type and Properties"
But how a content type can log in?
Am i missing something?I would be very thankful for any reply.
Developer / Drupal Ninja | Demotix.com
We are Demotix and we are looking for full time developers to become Demotix too!
Demotix (from demos/Δήμος, meaning ‘people’) is a multi-award winning photojournalism website and newswire: www.demotix.com
We've been called "Journalism for the 21st Century" (Telegraph), the HuffingtonPost thinks we "may change the way news is reported", and TechCrunch reckon we're "reinventing the newswire". Another way of describing us is that we're citizen journalism on steroids: truly empowering (and paying for) local story-tellers around the world.
Importing arbitrary data into ARC2 with RDFx module
We are working on importing profile information from social networks. I have been looking at the RDFx module, because it includes ARC2 as a data store.
How can we co-operate with Interactive Knowledge Stack?
Hi,
I came across this project.
http://www.iks-project.eu/
Is this something we should co-operate with so as to include parts of this project in Drupal?
Thanks
Schema.org mappings not saving
Hi all,
We are having a problem with our Drupal 7 site using RDFx and schema.org modules. The mappings aren't saving. So, we are using the "Article" type from schema.org. We have field called "Summary body" that we want to map to "description" property (actually from "Thing" but doesn't work with "articleBody" from Article type either). When we edit the field and fill in the "Summary body schema.org mapping: Property" field and save and edit again, the field is empty.
Semantic Web gathering @ BADcamp
For those attending BADCamp 2011 this weekend and are interested in meeting up, I'll be around from Thursday night til Sunday night. On Friday I'll be at the Core Developer Summit, and for the rest of the weekend I'll hang out in the chx Coder Lounge (except during the few sessions I plan to attend).
SPARQL Endpoint for local data and rdf/xml representation?
Hi,
I have recently started to test Drupal and are also a newbie regarding SPARQL and have some questions.
If I create my own content types and add rdf-mapping to those, is it possible to have a SPARQL endpoint for the content created? I know that I can query for example dbpedia, but is it also possible to query local data (eg. data in the local drupal site)? How do I do that if possible? I have read the IBM Developerworks articles which were really good but did not answer my question.
Also, if I create a field and want to map that to a resource in order to achieve rdf/xml like
Can I use my own ontologies?
In my content types I have created the mapping for my own ontology. myont:Product, myont:product_Description, myont:product_Picture, etc. If I try to execute a sparql query, which prefix should I use? Should I have to create a file with the specification of the namespace?
Thanks in advance.
Help removing default RDF
Hi everyone,
I have starte to learn drupal semantic I would like to ask you a doubt. I have installed restfull in my site, so I can see the rdf file of my nodes in mysite.com/mynodenumber.rdf. I have noticed there are date fields of the nodes (create, update, modified) in the rdf file.
Do you know if I can remove this?
Also If you know some drupal semantic sites, please leave a message with the url. It's good to have an example to follow.
Warn regards,
Villena
Schema.org Rich Snippets announcement and report on Drupal 7 semantic web tutorial in Austin
In case some of you missed the announcement last week, Google now supports RDFa in its Rich Snippets using the schema.org vocabulary. As I explained in my blog post, this is great news for Drupal 7 since it supports the RDFa syntax natively. I've put together a schema.org module for Drupal to make it easy for site admins to set up their pages in Rich Snippets (currently supporting the types person, event and recipe).
How to make my site's categories appear in Google results?
Hi,
I would like to make my site's categories appear in Google results.An example of this are the BBC categories.
http://www.google.gr/search?gcx=w&sourceid=chrome&ie=UTF-8&q=new+york+ti...
For example,you can see the categories "News","Learning English", etc
Has this nothing to do with RDFa,Google Rich snippets or microformats?
Thanks for your time
Schema.org wrapup and Feedback from Austin
Scor has been busy traveling over the past two weeks, attending the Schema.org workshop in Mountain View and giving a session on Semantic Web in Drupal at Austin. To let him catch his breath after all that traveling, we're postponing the bi-weekly Linked Data planning session to next week.
During the session, he'll report on what happened at the workshop and he'll relay the feedback from the folks in Austin.
If you are interested, feel free to join the conversation. Just ping me on IRC or through the Contact form and I'll make sure to add you.
Semantic Web Workshop - October 1st in Austin, TX
Just a reminder, we're having a Semantic Web workshop in downtown Austin this coming Saturday! Go to Eventbrite to register. Here's a bit of background info:
Workshop material
Microdata office hours
Since the usual folks on the Linked Data planning call can't join this week, I'll be holding microdata office hours instead.
If you develop field formatters in contributed modules and want to figure out how to enable microdata for them, I would be happy to help you figure it out. Join IRC to ask me questions... #drupal-html5 or #drupal-rdf (and ping me with 'linclark' to get my attention ;-)
Even if you don't use IRC, feel free to contact me and we'll figure out a way to work together on this.
Correct formatting of RDFa?
I'm learning/exploring RDF/RDFa in Drupal and something I see doesn't quite make sense... I have a pretty vanilla installation of Drupal 7 (v7.8) using the Bartik theme. On a page with a book and some info for the book, I have a Link field mapped to "owl:sameAs" which generates this code:
<div class="field-item even" property="owl:sameAs">
<a href="http://www.worldcat.org/oclc/1184647" target="_blank">
http://www.worldcat.org/oclc/1184647
</a>
</div>
