The EDIT Data Portal publishes taxonomic data data hosted in a CommunityStore either to a closed community or to the public at large. It has been implemented as a module for the content management system Drupal. The term “content management system” is somewhat misleading here: since the actual content is stored and managed by the CDM, ensuring scientific accuracy and reusability of data. Drupal offers a great deal of flexibility and can be extended almost indefinitely, making it possible to adapt the EDIT Data Portal to the individual needs of a community. Custom web pages, forums, and blogs are only a few of Drupal’s capabilities available out of the box, and there is practically no limit to the number of modules that can be added to enhance a site with for example image galleries. The layout and look and feel of the application can be easily adapted to fit any taste.

The EDIT Data Portal supports zoological and botanical names (support for viral and bacterial names should be available soon), as well as multiple concurrent taxonomies. Rules as specified by the nomenclatural codes ICBN and ICZN are built into the CDM, ensuring that taxon names conform to these standards.

User interface design was guided by the following design principles: provide easy access to all taxa and names; display all relevant information in one place where possible; and reduce complexity without compromising scientific accuracy. A challenge particular to taxonomy is keeping the user from losing his or her bearings while navigating through vast taxonomic trees; to this end, a sophisticated taxonomic tree browser has been developed to reduce confusion and make daily work with such trees more productive. A search function provides an additional way to access taxa.

Each taxon is represented by an individual page, which displays the list of synonyms, related taxa, occurrences, descriptions, media, and more. The list of homotypic and heterotypic synonyms is ordered historically and grouped by types; its layout resembles that found in printed publications. Images of protologues and of type specimens are linked directly from taxon names and synonym lists. In addition, taxon pages will allow users to contribute annotations as text or images.

Currently, EDIT Data Portals and CDM Community Stores are used to store and publish the work of the EDIT exemplar groups focusing on the taxonomic groups Cichorieae, Diptera and Palmae. Links to the demosites are found below.

CDM Dataportal Demo Sites

The capabilities and functions of the CDM Dataportal are demonstrated by the installations for each of the three EDIT WP6 exemplar groups.


Palmweb is a prototype portal for information on the diversity of the palm family (Arecaceae or Palmae).

Palmae DataPortal:

Discussion on requirements:


Cichorieae Portal

The Cichorieae Portal is being established as a convenient access to the existing knowledge about this difficult group of plants, based on authoritative taxonomic information.

Cichorieae DataPortal:


Diptera Portal

The Diptera Portal will serve authoritative taxonomic and other information on Diptera (flies and mosquitoes).

Diptera DataPortal:
