Decentralized Information Group
Decentralyze — Programming the Data Cloud, my occasional blog. I also direct the Information Roads Foundation.
2009. Two invited talks: RIF: Bringing Order to Chaos (RuleML 2009 Keynote), and Semantics for the Rest of us (ISWC 2009 Workshop Keynote)
2009. riftr is a RIF translation engine. Not currently working. source code.
2005-2009. RIF (Rule Interchange Format). I'm the staff contact for this Working Group. Currently a W3C Candidate Recommendation.
2007-2009. OWL 2. I'm the primary staff contact for the OWL Working Group. Now a W3C Recommendation.
2009. CommonScribe is a tool I wrote to make scribing meeting easier, for my Working Groups.
2009. revdoc is a tool I wrote to make publishing W3C Technical Reports easier. In particular, it made it practical for OWL to publish 13 interlinked TRs at the same time.
2008. XTAN (XML Transform-As-Needed) is the future of forward-compatibility and cheap interoperability, unless it's not. Maybe an RDF version would be better. source code.
2007. asn06 and asn07 were attempts to bridge the space between grammars (BNF, XML Schema) and ontologies (OWL), in service to RIF extensibility. source code.
2005. W3C Workshop on Rule Languages for Interoperability and the RIF Charter
2004. Semwalker, a server-side linked-data browser. A retrospective talk given in 2006. Source Code
2004. Ontaria A SemWalker installation intended to serve as W3C's central ontology directory.
2004. N3/Cwm tutorial (with TimBL and DanC
2003. Surnia was an OWL Full reasoner built using the naive approach of: throw it all at a first-order theorem prover. It can be useful to help see the limits of that approach, but it was only a few weeks work.
2003. OWL I stepped in as co-staff contact with Dan Connolly, on the Web Ontology Working Group.
2003. URIs. I worried a lot about Overload URIs. Experimenting with writing in wiki in those days.... (use "info" to just look at the last version I wrote?)
2002. LX, (Logic eXchange) a sort of pre-cursor to RIF, built into cwm. See Using Reification To Extend RDF.
2002. Thinking about Semantic Web architecture.
2002. CoWork ontology and tools
2001. Blindfold, a grammar-based system for translating among RDF serialization languages. (I have some more recent work on this concept, in Python, somewhere.)
2001. C++ SemWeb Library (mixed in with blindfold), and Perl SemWeb Library.
2001. The tag: URI Scheme (RFC-4151). This was my first reaction to encountering HTTP URIs used in RDF — to say don't! — before I saw the utility of linked data. Work on the RFC was essentially done in 2001, but it took four more years to get through the IESG.
2001. Various Writing.
My sister, Maya Wallach, runs a web site programming and consulting company called Flying Mountain. She also sells Phiten necklaces and Phiten bracelets and runs the Tracks & Tales Nature School in Duvall, Washington.
My father, Bret Wallach is a professor of human and cultural geography. He has an amazing collection of pictures on the web called The Great Mirror. I helped build earlier versions of the site, but this version was done by Maya.
My aunt, Dana Salisbury is a choreographer and multidisciplinary artist.
My grandmother, Anne Wallach, 1912-2005. (Born Anne Kael, known as Anna in my part of the family.)
