# SIG:GraphTechnologies

### From TEIWiki

As TEI is not a format, though many people think it is. It's a de facto standard that specifies Guidelines for document interchange. Actually the Guidelines are based on the XML but this is only one possible technical way of expressing the phenomenons.

**The aim of the Graph-SIG is to find a way of expressing the language phenomenons of the TEI in Graphs.**

- In the graph you can use multi-hierarchical annotations layers.
- Graph models are very easy to read and understand. So DH-People and “normal” scientists have a level of discussion in common.
- A Graph can be expressed as RDF so the step from a Graph to linked open data is easy to make.

The main goal of the TEI-Graph-SIG is to model the textual phenomenons of the TEI in a Graph and to develop routines to import TEI-encoded XML-files into graph databases.
