What is Tainacan?


Get to know Tainacan with our introduction video.

Tainacan is a software solution for building, managing and publishing digital repositories of any kind on WordPress. Manage and publish you digital collections as easily as publishing a post to your blog, while having all the tools of a professional repository platform. It is composed of a WordPress plugin, which is being developed on this repository, and an optional companion WordPress theme specially designed to produce beautiful digital exhibits. Try it out!


Easy install

  • As a WordPress plugin, Tainacan can be easily installed on and integrated into an existing WordPress website.

Metadata and filters

  • Use standard metadata or choose whatever set of metadata you want to describe the items in your collections. You can choose which metadata will be used as a filter when browsing the collection.

Faceted search

  • Browse (and let the public browse it) your collection using a faceted search interface with filters you have chosen.

Manage taxonomies

  • Manage vocabularies that can be used across all your collections.


  • Tainacan has its own default theme, which helps you present your collections in a beautiful and effective way as it is developed to incorporate all of Tainacan functionalities. However, it will also work with any WordPress theme. For developers, it will be easy to add Tainacan specific features to an existing theme.

API and interoperability

  • Tainacan implements a RESTful API (read and write) to allow other applications to interact with your repository. Expose you collection in different formats, such as JSON, JSON-LD and OAI-PMH. If your collection uses a custom standard, you can map it to well-known standards such as DublinCore.
