Tools currently in production:

1. ISOcat: an implementation of the ISO 12620:2009 standard and the Data Category Registry of ISO TC 37
2. LEXUS: a web based lexicon tool aiming at supporting LMF (ISO 24613:2008) among others

Tools currently under development:

1. RELcat: a companion registry to ISOcat allowing to store personalized (ontological) relationship among data categories
2. SCHEMAcat: a registry to persistently store schemata of any kind

Still available tools (outside of the MPI) on which I worked in the past:

1. Typological Database System: a web interface that provides integrated access to various typological databases
2. IPA Console: a Java WebStart application that allows to copy Unicode IPA symbols to the systems clipboard using an interface closely resembling the familiar IPA chart
