Dublin Core conference 2008 started

23. September 2008 um 12:20 2 Kommentare

Yesterday the Dublin Core Conference 2008 (DC 2008) started in Berlin. The first day I spent with several Dublin Core Tutorials and with running after my bag, which I had forgotten in the train. Luckily the train ended in Berlin so I only had to get to the other part of the town to recover it! The rest of the day I visited the DC-Tutorials by Pete Johnston and Marcia Zeng (slides are online as PDF). The tutorials were right but somehow lost a bit between theory and practise (see Paul’s comment) – I cannot tell details but there must be a way to better explain and summarize Dublin Core in short. The problem may be in a fuzzy definition of Dublin Core. To my taste there are far to many “cans”, “shoulds”, and “mays” instead of formal “musts”. I would also stress more the importance of publicating stable URIs for everything and using syntax schemas.

What really annoys me on DC is the low committement of the Dublin Core Community to RDF. RDF is not propagated as fbase but only as one possible way to encode Dublin Core. The same way you could have argued in the early 1990s that HTTP/HTML is just one framework to build on. That’s right, and of course RDF is not the final answer to metadata issues – but it’s the state-of-the-art to encode structured data on the web. I wonder when the Dublin Core Community lost tight connection with the W3C/RDF community (which on her part was spoiled by the XML community). In official talks you don’t hear this hidden stories of the antipathies and self-interests in standardization.

The first keynote that I heard at day 2 was given by Jennifer Trant about results of steve.museum – one of the best projects that analyzes tagging in real world environments. Data, software and publications are available to build upon. The second talk – “Encoding Application Profiles in a Computational Model of the Crosswalk” by Carol Jean Godby (PDF-slides) – was interesting as well. In our library service center we deal a lot with translations (aka mappings, crosswalks etc.) between metadata formats, so the crosswalk web service by OCLC and its description language may be of large use – if it is proberly documented and supported. After this talk Maria Elisabete Catarino reported with “Relating Folksonomies with Dublin Core” (PDF-slides) from a study on the purposes and usage of social tagging and whether/how tags could be encoded by DC terms.

At Friday we will hold a first Seminar on User Generated Matadata with OpenStreetmap, Wikipedia, BibSonomy and The Open Library – looking forward to it!

P.S: Pete Johnston’s slides on DC basic concepts are now also available at slideshare [via his blog]

Second day at MTSR

It is already a week ago (conference blogging should be published immediately) so I better summarize my final notes of the MTSR conference 2007: Beitrag Second day at MTSR weiterlesen…

The Steve.museum tagging project

13. September 2007 um 22:56 1 Kommentar

Steve.museum is a tagging project that has been active for more then a year by now. Unlike other artificial prototype-tagging-research projects it is based on real world data: works of art in museum collections. Moreover its not available only by pictures in research-papers but available at sourceforge (written in PHP). More news about the project can be found at the Mailing list and the blogosphere. I stumbled upon jtran’s blog and his report from ASIST SIG-CR workshop on social cassification that took place in Texas last year. Hopefully someone from the steve.museum team will participate in Dublin Core conference 2008 or some other event the I participate!

Nochmal Tagging und dann los

Bevor ich morgen nach Taiwan fliege (mit Zwischenlandung in Hongkong aber hoffentlich nicht so wie auf diesem Video), hier noch zwei Neuigkeiten zum Thema Tagging:

Auf der Dublin-Core Konferenz 2007 (DC-2007) in Singapur wird es eine von Liddy Nevile organisierte Session zum Thema Tagging geben. Angesichts eines fehlenden Permalinks für die Session, der Nicht-Nennung und Verlinkung der URL des im Abstract genannten Social Tagging wiki und des Tagesordnungspunktes “Election of leaders” kann ich mir allerdings eine Spitze Bemerkung nur mühsam noch verkneifen.

Noch interessanter ist die neueste Entwicklungen der Tagging-Funktion in LibraryThing. Unter der Bezeichnung “Tagmash” sind nun (soweit ich es auf den ersten Blick verstanden habe) gespeicherte Anfragen mit erweitertem Booleschem Retrieval über Tags möglich. Die Innovation liegt wie allgemein beim Tagging weniger in der Funktionalität als in der Umsetzung. Vom Standpunkt der Informationswissenschaft mag es keinen Unterschied machen, ob jemand seine Suchanfrage in einer speziellen Anfragesprache eingeben muss oder die Anfrage einfach zusammenklicken kann, aber in der Praxis liegen Welten dazwischen. Übrigens unterstützt LibraryThing ebenfalls bereits Möglichkeiten für hierarchische Tags (hier ein Beispiel) und terminologische Kontrolle. Die Reaktionen auf Tagmash finden sich am besten Google Blogsearch oder Bloglines (Technorati ist bei mir durch die Zumüllung ihrer Suchergebnisse mit Videos und Fotos erstmal unten durch).

Noch ein Hinweis in eigener Sache: Die kommenden Postings werden wahrscheinlich etwas kürzer ausfallen oder ich schreibe gleich in unserem Urlaubsblog.
