Toolbox is a data management and analysis tool for field linguists. It is especially useful for maintaining lexical data, and for parsing and interlinearizing text, but it can be used to manage virtually any kind of data. Toolbox is free to download and use. Toolbox is especially powerful for handling large corpora and dictionaries. It can handle a corpus of over a million words, and a dictionary of hundreds of thousands of words

At heart, Toolbox is a text-oriented database management system (DBMS) with added functionality designed to meet the needs of a field linguist. The underlying DBMS offers full user flexibility in the design of any type of database. But for ease of use, the Toolbox package includes prepared database definitions for a typical dictionary and text corpus.

Toolbox also has powerful linguistic functionality. It includes a morphological parser that can handle almost all types of morphophonemic processes. It has a word formula component that allows the linguist to describe all the possible affix patterns that occur in words. It has a user-definable interlinear text generation system which uses the morphological parser and lexicon to generate annotated text

A cross-platform XML editor that may be used to create and validate XML documents and associated schema. It fully supports XSL (both XSLT and FO), DTD, Schema (Relax RNG and W3C), Database, XQuery and CSS. OXygen XML Editor works with all XML-based technologies, including XML databases, XProc pipelines, and web services and comes with ready-to-use DITA, DocBook, TEI, and XHTML support.

Frequently updated and supported, and with a very large set of features, this software tool has proved popular with digital humanists.
