Semantic Web
This group was started at DrupalCon Barcelona 2007. How to integrate Semantic Web into Drupal? How can we make it easier for modules to implement Semantic Web meta-data in Drupal...
Abstracted Web Services API for Drupal 7
This is the beginnings of a design specification proposal for an abstracted API for implementing web services within Drupal 7. This allows Drupal to act as both a server and client for web services in any protocol medium (XML-RPC, RDF, RSS, JSON, etc). It is the combined efforts from a number of people at Druplicon including Marc Ingram, Scott Nelson, Nedjo Rogers, Dmitri Gaskin, etc.
Services API
Open Kalaif vs. Open Calais
Just read this article - does anyone know more about this Open Kalaif or is it just a reporter in a hurry with a spelling mistake? Did a google search on drupal.org and nothing turned up . .
Neologism, easy RDFS vocabulary publishing
FOAF, DC, SIOC, SKOS are famous vocabularies commonly used in the Semantic Web. Many other custom vocabularies exist and are created everyday. Vocabularies play an important role in the Semantic Web as they enable interoperability across various RDF data sources, and are used by RDF publisher and consumers who refer to them in their data.
$5000 Daylife Developer Challenge
I am very excited to announce the first Daylife Developer Challenge for building applications using the Daylife News Aggregation APIs. Folks hosting Drupal based websites on http://ecproject.org and http://comminit.com have built drupal pages/blocks/modules serving syndicated content using the Daylife APIs earlier.
The prizes are: a $3500 first prize and two $750 runner up prizes. The contest ends midnight of July 25th
Drupal Community / Social Networking Consultant | BoaB interactive
We are looking for export Drupal consultants who have experience implementing community/social sites. Expertise in Organic Groups and Taxonomy Access and similar is much sought after.
Basically we have a client who needs a community system to be used in an intranet setting. Multiple groups can be created and individual users can of course belong to multiple groups and create/edit/share content between groups.
Any semantic progress?
Hi all. Looks like RDF project and SPARQL project have become inactive. Whats happenning on the RDF front? How to we keep the momentum that was generated by Dries' talk at Drupalcon?

FP7 BoF on next Drupalcon?
FP7 is the EU instrument for funding research, see the introduction on wikipedia or go to the primary site You will notice the Drupal development can fit many calls in general but non in particular. The first goal is to figure out if enough people in the community are interested in EU funded Drupal research. I've made a list with some initiatives that looked relevant, but please be free to give your own opinion or to show your interest.

It would be good to start writing case studies or tutorials on how to build semantic websites with Drupal.
LOD Triplification challenge
Some unofficial note about the LOD Triplification Challenge was already posted here a little earlier, but now once we officially announced the challenge I wanted to use the chance to announce it once more officially ;-)
The LOD Triplification Challenge aims at expediting the process of revealing and exposing structured (relational) representations, which already back most of the existing Web sites, as well as raising awareness in the Web Developer community and showcasing best practices.
my.drupal.org
Thought it'd be a good idea to start a discussion specificially on how this might work.
This is a very rough outline from my first post on this subject Drupal.org the redesign - high level.
European Grant applications
This week I had a talk with Mixel Kiemen, who is an assistant at the MOSI research & teaching group at the Vrije Universiteit Brussel. It seems that he is in a better position to lead an effort for a European Grant application for Drupal development.
He started a group at http://groups.drupal.org/academics
Apparently there was to much overlap with http://groups.drupal.org/drupal-research-and-academia so he joined this group.

[Final] Views plugins to output node lists as XML/RDF/JSON/XHTML
Abstract
This is a proposal to extend Views with the goal of enabling Drupal semantic data sharing and interop out-of-the-box by writing views style-plugins that can spit out node lists as XML, OPML, RDF, JSON, and XHTML.

For example if you created a view with a list of events and details, you could with one click generate a page containing events in the hCalendar microformat or as items in Exhibit JSON format. Similarly lists of user profiles could be output as FOAF profiles in RDF or in the XHTML hCard format. Lists of forum posts could be output as RDF documents using the SIOC vocabulary. Or a simple list containing books from a personal book collection could be output as OPML. This idea is motivated by the accelerating activity around Semantic Web data sharing. The ultimate realization of this idea would be to enable a Drupal site operator to share datasets from her site already constructed through the Views UI in one of several open and reusable formats based on XML, XHTML or JSON, which would be consumable by other Web agents.
Triples Stores Integration With Drupal
Hi All,
I have recently been looking into drupal's intiative around semantic web. I also looked around the modules contributed in rdf and the api's associated with it.
Regarding it, i would like to open a discussion around using 3rd party triples stores to integrate with drupal and rdf api's available. Right now the triples are stored in RDBMS lets say mysql but looking at this approch, i doubt on the scalibility factor for it. A case when lets say 1 billion triples are there in the store, how the performance will be in that scenario ?
LOD Triplification Challenge at I-Semantics 2008
There is a Semantic Web challenge being organized for the I-Semantics 2008 conference in Graz, Austria. Drupal is one of the open-source Web developer communities being targeted.
The aim of the challenge is to expedite the semantification of Web
applications and datasets as well as raising awareness and showcasing
best practices.
The challenge is open to anyone interested in applying Semantic Web and Linked Data technologies. This might include students, developers, researchers, and people from industry. Individual or group submissions are both acceptable.
PHP APIs for RDF
Hi there,
I'd like to start a thread to discuss about available RDF APIs for PHP.
I took a look at Benjamin Nowack's ARC2 (http://arc.semsol.org). It looks sound and it's already used in several projects. It features several i/o parsers/serializers, an integrated RDF store, SPARQL query engine (didn't read anything about compliance with W3C DAWG test cases...), SPARQL endpoint, some simple inferencing and there are also some plugins I didn't look at for now.
Triplify
hi,
for a first simple support for RDF export, I'd like to point you to http://blog.aksw.org/2008/triplify-expose-semantics/ and http://triplr.org.
I think a quick generic RDF support for nodes will be easy to add.
I also recommend to keep the current node URI scheme and add support for content negotiation as described in [1]. So, if a client sends the request header "Accept: application/rdf+xml", the server just returns an RDF version of a node, otherwise it will get the ordinary HTML version, possible polished up with RDFa or microformat tags...
Regards,
Andy
Global News Content Module - Stories, Photos, Quotes, Connections
Moved to official ideas list: http://drupal.org/node/237907
I want to propose a project for building a module that pulls news content from a global news service called Daylife (http://daylife.com)
Daylife is a global news aggregation service that offers an Open API platform called DayPI (http://developer.daylife.com) for any developer, blogger, news service to pull stories and photos about any topic in the world. The API returns data in XML, JSON and PHP serialized formats. You can read the Daylife About page at http://www.daylife.com/page/about to learn more about the company. All platform documentation is on http://developer.daylife.com/docs
Memetracker module proposal
Summary:
I want to write two modules for Drupal as part of Google Summer of Code. One called meme_tracker and the other called machine_learning_api. The meme_tracker module will use the machine_learning_api to intelligently filter and group content from both internal and external content sources. The module's purpose is to find and display to a community in real time the most interesting conversations and memes within the community as they emerge.
Hello Drupliers. My name is Kyle Mathews. I'm a grad student in Information Systems at Brigham Young University working as a research assistant to several faculty members here. We are studying how and where social software can be used in education.
In the past eight months, I've built a number of classroom websites using Drupal. I've learned a considerable bit about Drupal in the process, became very involved in the community, and am writing a module (writing_assignment -- still a work in progress btw). I've loved most everything about Drupal but have found Drupal is missing an important component for building the perfect social learning website. This itches. So, in the best open-source fashion, I'm applying to Google Summer of Code to scratch my itch.
RDF in other open source CMS's
Today I talked with Thomas Hochhaltinger from ebSemantics, a project of "Smart Information Systems", an Austrian company that developed MyOntology.org a collaborative ontology designing platform with ontologies for consumer electronics goods.
Tag the net with Open Calais
Reuters released a web service called Open Calais. It is built on clear forest technology that has been around for a while.
You can throw text at it and get tags organized by country, personalities, industry terms, ... in RDF format back. It is of better accuracy than http://tagger.flaptor.com/findtags, http://tagthe.net or yahoo terms extraction API (http://www.programmableweb.com/api/yahoo-term-extraction, http://drupal.org/project/yahoo_terms)
You can try it here:

GRDDL, Drupal, & Microformats
Hey all,
How many of you know about GRDDL ('griddle')?
If you've seen the acronym around but haven't read the spec, then you are missing out.
In short, it's a W3C recommended way to post links to XSL stylesheets in HTML and XML documents.
Those stylesheets are specifically designed to produce RDF/XML from a target document.
So what, you might say.
Well: these GRDDL transformations can be done for an individual document; or an entire xml namespace / xmdp (microformat) profile.
Semantic Drupal FP7: Code sprint series
Last week at Drupalcon in Boston I realised that it's just not possible to apply for a development FP7 (the 7th Framework Program of the European Union) for Drupal. Things are going so fast that any plan would be obsolete before the project could get granted. That's why I think it would be the most interesting to do a proposal for a series of expert meetings throughout Europe that brings together people to discuss their implementation of the semantic web in Drupal, every time followed by a code sprint.

RDF as it applies to field structure in core
KarenS has kicked off a discussion on CCK field structure for core in D7. It's also webchick's itch of the week.
David Strauss is already commenting, and has experience in RDF from the Internet Archive, but it would be good to have other experienced people giving this the once over. Since these fields are likely to be a major way that people "transparently" create subject/predicate/object relationships, we better get this right (and performant, working on shared hosts, etc. etc.).
Drupal 7 and Semantic Web Core
In regards to the Semantic Web developments announced recently about Drupal 7, I have posted a blog entry at SitePoint and also posted to the Linking Open Data mail list.
Drupalcon Boston 2008 mashup demo
This is the 5-minute "video from the future" demo presented by Dries in his State of Drupal keynote presentation at Drupalcon Boston 2008. The video demonstrates some of the mashup capabilities of an RDF and SPARQL-enabled Drupal as envisioned by Dries for the upcoming Drupal 7.x release. The version of the demo below includes the original narration by Ben Lavender (the audio from Dries's actual presentation is also available - the RDF material starts after the 52m:30s marker).
Drupal RDF Schema proposal
I'd like to share some quick thoughts on how Drupal Data could be described in RDF. The attached schema represents the mappings between the current Drupal data structure and the proposed RDF Schema, reusing existing ontologies such as Dublin Core, FOAF, SIOC and SKOS.
The green circles represent the Drupal objects (node, revision, user, role, term), with their equivalent RDF class. The rectangles are the values used in Drupal. It's important to differentiate a class from its actual instances (resources) which are each defined by a unique URI, see the examples below. This schema is meant to be simple, incomplete, and to show the main core features.
Comment and Node are 2 different elements in Drupal, they can be combined in the same Class with the recursive property sioc:has_reply (Comment as Node). Node and Revision objects are separate here as they are in the Drupal Data structure, but they could fundamentally be merged as well.
I presented SIOC at DrupalCon Barcelona, and showed how it can be used to describe online communities. The SIOC sioc:Item class which I used here as equivalent of a Node is a broad Class with many sub-types: AddressBook, AnnotationSet, AudioChannel, BookmarkFolder, MailingList, MessageBoard, BlogPost, BoardPost, WikiArticle... See the SIOC Types Module for more details.
Web Services in Drupal 7
Just a quick note that nedjo posted a note about Services module going into core. This would allow use of XML-RPC, JSON, RSS, REST, SOAP and more to be loaded through a common Services API.
A Code Sprint will take place in Boston this coming Friday that will focus on the inclusion of this new Services API.

Details:
1) Html and design work is complete.
2) Partial site has been built.
3) Required back end where corresponding consumer Inputs (answers to questions etc.) will generate outputs in a Personal Plan / Format for the person.
4) Project is Patent Filed.
Potential RDF use cases for Drupal
Following up on my previous post introducing the in-progress RDF API for Drupal 6.x, I'm going to be, bit by bit, posting some of the materials that I've earlier put together internally for the project this is being developed for. Development of this project is supported through M.C. Dean and MakaluMedia on behalf of their clients.

RDF API for Drupal 6.x
I've been working on an RDF API for Drupal 6.x for a few months now, but have been reluctant to much discuss it publicly until such time that I had something that was viable and (dare I say it) usable. Given that I've been fortunate enough to recently find funding for part of this work, and that certain key people (thanks Boris and Ivan) have encouraged me to be less of an introvert, I will in the immediate future be doing a series of posts about the project.

RDF data standardization for Drupal
A number of projects are now working with RDF and the Semantic web.
They may not all share the same RDF store, but for data interchange, they should all share the same RDF structure. RSS, ATOM and OPML are standards, but RDF can be rich.
Here's a quick outline to get this page going:
Question 1:
Should we be considering OWL?

EU Objective ICT-2007.4.2 (ICT-2007.4.4): Intelligent Content and Semantics
The ICT - INFORMATION AND COMMUNICATION TECHNOLOGIES workprogramme from the European commission has calls for applications that could fit a Drupal project. Especially Objective ICT-2007.4.2 (ICT-2007.4.4): Intelligent Content and Semantics is very interesting, anybody interested in collaborating on a grant proposal for this?
Target outcome
Medium term:
a) Advanced authoring environments for the creation of novel forms of interactive and
expressive content enabling multimodal experimentation and non-linear story-telling.
DrupalCon
DrupalCon, was very successful for the SemanticWeb.
I was very surprised by the attendance of my talk - around 70 people - and the group meeting afterward had some very knowledgeable, motivated, and interesting people. I am really looking forward to fleshing out things here.
Suggestion for process to add more semantic information to drupal
With the process of Action Learning i made good expirience, so i want to suggest it for us although.
It's rather easy, and we did a lot of it until now.
To write down all steps helps us to get new people on board, they can read what the history and the aiming is.
The steps are:
1.) gather information about semantic in drupal
2.) get an understanding of semantic in drupal - with other words what do you lack of?
3.) priorisize identified topics - what is urgent for you? what is realistic?
Ideas gathered at DrupalCon Barcelona 2007
This is the digest of the brainstorming session we had at DrupalCon Barcelona 2007, Sat 22nd.
How to implement Semantic Web tools for Drupal in order to make it easier for any module to make use of Semantic Web advantages? The aim is to be as general as possible so that any module can use some Semantic Web facilities available without having to implement its own RDF store for example.
