Thema is a category scheme based on hierarchical code structures and the BIC classification scheme. It has been developed by EDItEUR who also created ONIX. EDItEUR released their latest version of Thema (Thema 1.4) in April 2020. It has 150 new subject codes and 550 new qualifiers.
Thema has improved the traditional BISAC code by allowing you to add more codes over time and deliver more precise information. Products are easier to find, more relevant and better categorized.
What are the main advantages of using Thema?
Thema provides an international standard for subject classification. This is crucial in an increasingly international industry. Using different schemes can cause unnecessary complexities and a loss of precision and data. Thema allows more control over classification and therefore increases discoverability and sales.
Users only need to go between their own scheme and Thema, rather than back and forth through numerous other schemes.
Thema uses qualifiers which help to provide detail and context. Qualifier categories include Geography, Language, Time Period, Educational Purpose, Interest Age and Special Interest.
For example, the Geography qualifier has country specific codes to suit local markets. The geography qualifier also benefits from ‘national extensions’ which is another level of detail.
It is easy to add new codes so Thema can keep up with new publishing trends
Thema is free to use and straight-forward to implement. It is very similar to the established BIC scheme. Click here to find out more about Thema and how to use it.
