The Thema project was launched at the Frankfurt Book Fair in 2012, and a pilot draft of Thema version 0.9 was published on 19th April 2013. Early development was guided by a Thema board and a technical committee, and drew upon earlier work with an internationalised version of the BIC subject scheme. Thema goes further to ensure that it is internationally relevant, by combining a robust selection of shared subject categories with an expansive list of subject qualifiers which can contain national variants and extensions. Thema provides a structure that has global application while meeting local needs.
The first ‘live’ version of Thema was launched in late 2013, and version 1.0 was presented (PDF) at the CONTEC Conference during the Frankfurt Book Fair 2013. An initial spreadsheet (in English), a set of basic user guidelines, a mapping from the BIC 2.1 subject scheme to Thema, and a simple interactive category picker (with partial translations in six languages) were made available on 31st October 2013. Full translations of the scheme plus an extended multilingual version of the interactive picker (including full translations in German, French, Norwegian) and other resources followed. Further translations became available during 2014. The ‘sunrise’ date – the first date on which it was reasonable to include Thema classifications in product metadata (eg in ONIX files) - passed on 31st December 2013, and many implementations are now available in software vendors’ product management systems.
Thema version 1.1 – improved with around 125 extra categories and numerous other small refinements was launched on 30th November 2014 (initially in English only, though translated resources have been added since then, and further translations will be available soon). Version 1.1 is 'additions only', meaning that old metadata records need not be revised, but the new categories added provide for improved mappings from legacy schemes and greater precision in classification of children's and scientific titles in particular.
Thema is managed by EDItEUR through a number of national interest groups and an International Steering Committee, in a similar manner to ONIX for Books. The elected chair of the Thema International Steering Committee is Howard Willows (of Nielsen Book, though in this case representing the UK Thema national group). The scheme is free of charge for all to use, subject to EDItEUR’s normal, highly-permissive licence. No registration, fee or membership is required to implement and use Thema.
