Tainacan is a technological solution for the creation of digital collections on the Internet. Designed to meet the reality of cultural institutions, it is a free software that allows the management and publication of digital collections in an easy and intuitive way. It can be used to develop repositories and digital libraries, as well as communication, exhibition, and digital collection dissemination actions.

Management & Publishing

Tainacan is a WordPress plugin and theme. This means that to be able to use Tainacan, you must have an active WordPress installation. WordPress has an administrative panel that allows the user to manage and publish his collection. It is through the panel that different user profiles can be created, with different levels of access to the collections, as well as different web pages for the communication of the collections.

Easy Setup

The repository consists of collections that are made up of items. Items can be added via bulk edition or individually, directly from your computer or externally via importers. According to the needs of each collection it is possible to configure taxonomies, metadata and specific filters. All activities performed in the plugin are logged and listed, so they can be verified by moderators.

Faceted Search

Explore your collection (and let visitors explore) using the faceted search interface with filters of your choice.

Organization & Publishing

Use a predefined metadata standard or freely define the appropriate set of metadata to describe the items in your collection. In addition, choose which of this metadata will be used as filters (facets) to explore your repository.

Manage Taxonomies

Manage vocabularies (controlled or not) that can be shared across all your collections.


Tainacan’s default theme makes it possible to publish and present collections in a beautiful, efficient and responsive way (works on any screen size and format).

But using the default theme is not obligatory, the Tainacan plugin also works with any WordPress theme. For developers, it is easy to add support for Tainacan features to an existing theme.

API & Interoperability

Tainacan implements a RESTful (read and write) API that allows other applications to interact with your repository. Expose your collections in different formats, such as Json, JsonLD, OAI-PMH.

If your collection uses a custom metadata standard, you can map it to metadata standards such as Dublin Core, among others under development.
