TEI Libraries SIG
The Text Encoding Initiative Special Interest Group on Libraries (TEI Libraries SIG) formed in 1999 in response to a need to codify library-specific text encoding best practices based on the TEI. It also grew out of a DLF-sponsored initiative, the TEI Task Force. Substantial overlap between the DLF Task Force and TEI Libraries SIG have inspired collaboration to meet common goals including the creation of:
- Best practices that encourage the consistent and predictable encoding of TEI documents
- Tools for libraries to use in the creation and publication of TEI documents
In 2008, the TEI Libraries SIG and DLF TEI Task Force partnered to overhaul the Best Practices for TEI in Libraries, published in 2011 with version 3.0. This edition updated sections on the widely adopted encoding “levels,” the TEI header designed to support interoperability between text collections, and the use of complementary metadata schemas such as MARC and MODS.
Responsibility for the maintenance of the Best Practices and accompanying technical specifications has migrated to the TEI Consortium.
