Open Source Metadata Management Software

Colectica provides several Open Source software packages
for working with open standards based metadata.
 

Metadata Converters

The Metadata Converters project provides open source utilities that convert among various metadata formats. The first utility converts Blaise(r) source code to DDI 3. Thank you to the National Institutes of Health and the Canada Research Data Centre Network for their support in developing this utility.

Colectica DDI Agency Registry

The Colectica DDI Agency Registry allows you to deploy the DDI Registry software on your own infrastructure to run your own registry service. You might want to do this if you would like to provide your own delegation and resolution services, instead of relying on the DDI Alliance's registry service. The source code for the DDI Registry is available under the LGPL, an Open Source license.

Colectica DDI Resolver Libraries
