As discussed in today's teleconf this is probably a good time for people to start introducing themselves per mail to the other members of working group. This applies to both new and old WG members to get known to each other... I'll make a start. I am using the same structure we used in RIF for self-introductions: At the start of your introduction, please state "Principal" or "Alternate" representative of your organisation, to help people begin to form their picture of the group. After that, the topics one generally covers are: -- a bio summarizing experience you have that's relevant to the work of this group -- as much contact info as you care to share on this public list -- what you expect to get out of this WG -- what you hope/expect to contribute. Looking forward to a productive SPARQL working group! Here goes my own self-introduction: ======================================================================= -- Role: co-chair, alternate for DERI -- short bio: I obtained my PhD in Computer Science at the Vienna University of Technology, Austria, in 2003 working on AI Planning and Non-monotonic Reasoning. From 2003 to 2006 I worked at University of Innsbruck in the areas of Semantic Web Services, Ontologies, Rules & Query Languages and Logic Programming. While there, I started getting involved in standardisation work in rules languages (WRL W3C member submission). After that, I worked for one year at Universidad Rey Juan Carlos, Madrid under a "Juan de la Cierva" research award and joined the Digital Enterprise Research Institute (DERI) at National University of Ireland, Galway in April 2007. Previous experience in W3C groups: I am a member of the W3C RIF (Rule Interchange format) working group where I co-edit the Datatypes and built-ins draft (e.g. also keeping an eye on staying "compatible" with SPARQL's FILTER functions) and have been a member of the RDB2RDF XG until end of last year. I am W3C Advisory Committee representative of DERI. Experience/work with SPARQL: I have published about and implemented prototypes of translating SPARQL to extended Datalog rules, including proposals for extensions such as "SPARQL-extended" RDF graphs or aggregates [1,2] I reviewed the current SPARQL spec on behalf of DERI. Recently, I have worked on combining SPARQL with XQuery, [3] I have given several courses and tutorials on SPARQL and RIF at conferences, summer schools and in university courses, e.g. cf. [4] 1. A. Polleres: From SPARQL to rules (and back). WWW 2007: 787-796 2. A. Polleres, F. Scharffe, R. Schindlauer: SPARQL++ for Mapping Between RDF Vocabularies. OTM Conferences (1) 2007: 878-896 3. http://xsparql.deri.org/ 4. http://www.polleres.net/sparqltutorial/ -- contact info: all my contact data can be found at http://www.polleres.net/ -- what I expect to get out of this WG A stabilized upwards-compatible version of SPARQL that adds a reasonable set of features driven by user-demands and that can be achieved within the chartered duration. Evolve SPARQL to a more mature and useful query language, by adding features such as data manipulation constructs and aggregates, etc. as mentioned per charter. -- what I hope/expect to contribute. <chairhatOn>Help the group reaching its target by being a responsible co-chair of the group. Liaise with RIF and OWL wg to see how far we can bring the standards closer together with still remaining upwards-compatible (e.g. by Interoperability mechanisms as mentioned in the charter)</chairhatOn> <derihatOn> Together with Alex (principal representative for DERI) contribute our own experiences and feature suggestions to SPARQL, which mostly comprise small but useful extensions experienced from our practical experiences. </derihatOn> ======================================================================= best, Axel -- Dr. Axel Polleres Digital Enterprise Research Institute, National University of Ireland, Galway email: axel.polleres@deri.org url: http://www.polleres.net/
