close subject identifiers for Subj3ct
  • http://www.topicmapslab.de/projects/subj3ct


Project category: PSI registry service
Project status: Beta


Subj3ct is an infrastructure technology for Web 3.0 applications. These are applications that are organised around subjects and semantics rather than documents and links. Subj3ct provides the technology and services to enable Web 3.0 applications to define and exchange subject definitions.

Subj3ct works by allowing you to register URLs that act as identifiers for the things you want to talk about. Subj3ct also encourages the registration of other web resources that contain content about a particular subject. Subj3ct is also a platform that provides an API to allow applications to find subject identifiers and their related resources.

In Musica migrans we mapped the life courses of musicians in the 19th century. Topic Maps provides us the flexibility we need to model the diversity in the lives of the artists.
