Emdros is an Open-Source text database engine for analyzed or annotated text. It is applicable especially in linguistics, corpus linguistics, and computational linguistics. Emdros has wide applicability in fields that deal with analyzed or annotated text. Application domains include linguistics, publishing, text processing, and any other fields that deal with annotated text. Emdros provides a conceptual model of text which can be quite liberating to use once it has been grasped. Meta-data may also be stored, so long as there is some textual element with which it can be associated.
