The final report of the DEREKO project (ps.gz pdf) outlines the DEREKO linguistic annotation concisely in chapter 3.

Details on the kind of information annotated in DEREKO, and on the way this information is presented as an extension to the XCES encoding standard, are given in the two following manuals:

• Frank Henrik Müller (2002). Shallow-Parsing Stylebook for German. Technical Report. Seminar für Sprachwissenschaft, Universität Tübingen. (ps.gz pdf)

  The Shallow Parsing Stylebook for German explains the syntactic annotation at chunk, topological field, and clause level. It focuses on explaining the strategies adopted to annotate unrestricted German language robustly and reliably. It includes a discussion on phenomena out of scope of the DEREKO annotation.

• Tylman Ule (2002). DEREKO Linguistic Markup. Technical Report. Seminar für Sprachwissenschaft, Universität Tübingen. (ps.gz pdf)

  The DEREKO Linguistic Markup manual explains all other aspects of annotation, including POS markup, and tokenisation. The manual also shows which XML elements and attributes encode which phenomena for all DEREKO annotation within a sentence, including shallow parsing.
