Leobard's blog

It has happened! The Sesame developers finished the first beta of Sesame 2.0. This day marks a great moment in RDF development, as we have a successor to the very popular sesame1 server. Leobard says: well done guys, gratulations, enjoy, cherish, drink beer, a good reason to do mardi gras. Here the full annoncement, as received via e-mail:

We are ecstatic to be able to announce the first beta release of Sesame
2.0! Sesame 2.0-beta1 marks the end of architectural changes to Sesame 2
and allows us to focus on adding features and fixing bugs, and you to
finally see the Sesame 2 API as it is meant to be. You can find the
latest version in the download section at http://www.openrdf.org/ .

So what’s new in Sesame 2.0-beta1 compared to previous alpha releases?

* Repository, Sail and Query APIs stable.
We have moved from alpha-stage to beta-stage, meaning that the
core APIs, the interfaces and method signatures, are now frozen
and stable. This ensures that you as a developer will be able to
upgrade to future releases without fear of breaking your
application. See the JavaDoc API documentation and the user
documentation for more details.
* Improved Context Support.
We have improved the way Sesame handles contexts, allowing
developers to freely access any combination of zero, one or more
contexts in a single repository. Use of Java 5’s vararg feature
ensure a flexible, easy-to-use API.
* Sesame 2.0 Web Client.
beta1 features the first release of a web client for Sesame
servers. This web client can be deployed as a webapp and can be
used to conviently query and modify a Sesame repository running on
a (remote or local) Sesame 2.0 server.

For a more complete and detailed overview of changes, see the ChangeLog
at http://www.openrdf.org/ .

Of course, we would not call it beta if there were not some things
missing as well. Our ToDo list includes:

* A MySQL storage backend is under development but not yet available
in this rlease.
* Custom inferencing is not yet available.
* The SPARQL query engine does not yet support ordering and a few
other language features.
* Fine-grained security on repositories is not yet available.

As remarked before, this beta release marks an important step in Sesame
2.0 development: instead of focusing our development efforts on the core
structure and architecture we can now start paying attention to
(aforementioned and other) features. You can expect regular beta
releases as we add more of the ‘good stuff’.

Of course, we owe a great debt to the many contributors and
co-developers of Sesame 2. Thank you all for your patience, and we hope
you are as pleased with the result as we are.

Deliriously yours,
the OpenRDF development team

back to work, back to the web, just sitting on my couch with Rinne, a typo 3 guy who was with the T3BOARD07 – a snowboarding week of typo3 geek and geekines.

watch their amazing video of a week of snow and party…

Colorful and entertaining report from the #1 TYPO3 event of the year!. T3BOARD07 was held in France, Les Deux Alpes, last week in January – the 6th time! 130 participants from 10 countries in Europe. You will see snow, people, girls, football, tour de chambres and what was on the agenda for the lucky ones. And some extra gags are thrown in.

THE VIDEO

Hey, we should do the same with Semantic Desktop in Europe. The Semantic Snow 2008 – who is in?

The word is out there – the german “Technology Review” magazine, a partner of MIT’s technology review, has published an article about the semantic desktop and myself in its februar issue.

If you happen to be in a german-speaking country like Germany, Austria or Switzerland, go to a good bookstore and buy the february 2007 issue. The article sums up my idea of a Semantic Desktop very good, and they also have nice articles on the future of food. The keypoint is, that Semantic Web is a good idea, and Semantic Desktop can help start it.

Gordon Bolduan interviewed me, and I will publish a photo of him interviewing me (which I made) later in February – because I am going on holiday now! see the next post for more…

Did you ever ask yourself why you can’t find anything on your own computer, but can find stuff in the internet? Its the great search engines.

On the desktop, the Nepomuk project is aiming to enhance desktop search with semantic features. So additional to asking “where are these files with ‘money'” you can ask for things related to job offers within the last month.

Sebastian Trüg (whom you may know because you have been using K3B to burn CDs, watch the “about” window of this KDE app) is leading the Semantic Desktop integration for KDE, and he connected us with many other people, for example Jos van den Oever from the Strigi project.

We have set up a wiki page with plans for the future, and will try to integrate RDF search with fulltext search. This would allow a very generic, “technically beautiful” solution to data indexing, RDF is very generic and reusable and fulltext-indexing is quite handy already.

Pray for us, hold your thumbs, if all goes well, we will agree on one standard and desktop search will rock and roll.
