Marmotta leaves the burrow

25/11/2013, 18h27

Although Jakob literally saidthe podling is leaving the nest”, I think what we are actually leaving is the burrow to set sights higher. After 11 months under incubation, finally last week Apache Marmotta has become top-level project of the Apache Software Foundation. Thanks all who have contributed to it!

I think Sebastian has already written a great summary of the story behind Marmotta so far. But this does not end here, not all! Now the project has to demonstrate the potential of Linked Data technologies going to the next level. So I invite all potential developers/researcher/users that are reading these lines to join us in the further development of Marmotta.

RedLink GmbH

Finally this week RedLink GmbH is going live online. Beyond the simple fact of releasing the web site, behind there is much more. After we incorporated the company in March, last months of hard work with our first customers and partners have led us to understand what RedLink actually is, and how we see semantic technologies going to the next step.

RedLink GmbH

In Redlink our team is committed to the development of Apache Stanbol and Apache Marmotta and to the continuous growth of these projects as well as to their integration with Apache Solr. These are the fundamental technologies behind our proposal to help enterprises for making sense out of their data.

I encourage you give a try our demo with an open mind. Beyond the bounds that a standard setup could offer, the real potential of RedLink comes with the high customization possibilities. So don’t hesitate to sign-up to access a more advanced experience.

Apache Marmotta 3.0.0-incubating released

26/04/2013, 19h34

Finally today we managed to release Apache Marmotta 3.0.0-incubating, in which we’ve been working on for the last few months. You can download the release or use the maven artifacts available from the central repository, as you prefer.

This is the result of an important effort on two aspects: On the one hand, an engineering work to extract and improve the Linked Data capabilities we were already offering in LMF. On the other hand, we went through a intellectual property clearance process that I personally found pretty interesting. This release starts what we think it could be a successful open source project to bring Semantic Web / Linked Data technologies to the next level for the industry.

the Marmotta will be with you... always

And remember, the Marmotta will be with you… always. Thanks everybody!

LMF 2.6, towards Apache Marmotta

15/02/2013, 18h55

We’ve just announced the publication of Linked Media Framework 2.6.0. This release brings many improvements that the Salzburg NewMediaLab team have been working in the last months. And it’s also an important milestone towards starting to incubate Apache Marmotta, previously known as Linda.

So, if you have time and want to play with Semantic Web technologies, give it a try!

Time for a redesign

12/02/2013, 22h53

After fourteen years of existance, and more than four since the last major update, I think it’s time for a whole redesign of my personal web page to align it according to the current trends.

The Web has significantly evolved, but my design skills not. But I don’t want to use an impersonal theme already used by many people. I want to have something which represents myself better. In addition, I’d like to provide better support for different devices without a complex server-side infrastructure, I wanted something much more simpler. So last few days I’ve been reading a bit about RWD. After playing with some frameworks and tools such as foundation or bootstrap, finally I’ve decided to use tuktuk (by @soyjavi, tapquo) given its simple and effective usage of different technologies: HTML5, CCS3, ooCCS. With a really small effort, although there are many details to polish, I’m very happy with the result; hope you like it too!

Linked Media Framework 2.2.0

6/07/2012, 16h25

Since I joined Salzburg Research, we have been working very hard to improve the Linked Media Framework (aka LMF). And today we have achieved an important milestone releasing the version 2.2.0.

The Linked Media Framework is an open source Linked Data server which offers some advanced functionalities, such as transparent Linked Data caching, querying, reasoning and versioning. Within this new release it has now been extended to a complete Linked Data Publishing suite that you can use for a number of frequent tasks: Linked Data publishing from legacy formats, Semantic Search over your own data and SKOS Thesaurus managing. Check the full changelog for further details.

For this purpose, the LMF installer offers a combined and pre-configured set of tools, including, apart of LMF of course, Google Refine and Apache Stanbol. This integrated tool suite simplifies the interaction between these components, making much easier publishing Linked Data with our framework.

As usual, all feedback would be welcomed, both from industry and community. Thanks to the whole team for their superb work!

Definitively yesterday was my last day working at CTIC. In fact, we’ve worked until the last minute. It has been an honor to have the chance to share this time with people so well technically skilled, but even better people; some of them friends for life. But after more than six years there, I think now it’s my time for a change.

Thus next week I’ll move to Salzburg, where in May I’ll join Salzburg Research to work with Dr. Sebastian Schaffert at the Knowledge and Media Technologies department. I’ll join a very innovate team where I could apply my research on Linked Data to a more platform-oriented approach, initially on projects such as Linked Media Framework or Apache Stanbol.

Finally, an important change in my life. I leave in Asturias almost everything that I know, and by sure I’ll miss a lot my family and my friends here. But I feel I need this change, which I’m sure would be an enriching experience in many aspects.

See you then in Salzburg!

Easily document your vocabularies/ontologies with Parrot

30/06/2011, 15h15

After several months of development within ONTORULE project, today Tejo has finally announced that Parrot is online. This tool is the natural evolution of others, such as SpecGen or Neologism ; not better, just different. It adds the possibility to generate documentation from several artifacts, not only vocabularies/ontologies, but rules too.

Since the tool is also provided as online service, it introduces an interesting option: easily document your vocabularies/ontologies backed on this service. Based on the recipes it’d easy to write the necessary rules on your .htaccess to use Parrot in this way:

RewriteEngine On
RewriteBase /exampledir
AddDefaultCharset utf-8
AddType application/rdf+xml .rdf
AddType application/rdf+xml .owl

# Rewrite rule to serve HTML content from the vocabulary URI if requested
RewriteCond %{HTTP_ACCEPT} !application/rdf\+xml.*(text/html|application/xhtml\+xml)
RewriteCond %{HTTP_ACCEPT} text/html [OR]
RewriteCond %{HTTP_ACCEPT} application/xhtml\+xml [OR]
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/.*
RewriteRule ^example$ [R=303,L]

# Rewrite rule to serve RDF/XML content from the vocabulary URI if requested
RewriteCond %{HTTP_ACCEPT} application/rdf\+xml
RewriteRule ^example$ example.owl [R=303]

# Rewrite rule to serve the RDF/XML content from the vocabulary URI by default
RewriteRule ^example$ example.owl [R=303]

This configuration supposes that your vocabulary/ontology has as namespace, and the location of the source file is But you can customize it as your convenience.

For instance, the documentation for SIOC would be this . And based on the mappings provided by, Parrot also generates documentation from the most popular prefix of a vocabulary, such as for FOAF.

Please, check the full features list . And as usual, any comment is very welcome !
