We're concentrating on Kuha2 nowdays, see https://bitbucket.org/tietoarkisto/workspace/projects/KUH

Kuha is a lightweight OAI-PMH Data Provider implementation. It is written in Python with The Pyramid Web Framework.

• All six OAI-PMH verbs
• Support for many optional features, including
  • Deleted records
  • Resumption tokens
  • Set hierarchies
• DDI Codebook to Dublin Core crosswalk

Set up a virtual environment (recommended).

$ virtualenv env
$ . env/bin/activate

Install the package and dependencies.

$ python setup.py install

Make a copy of the example configuration file and customize it. The available settings are documented in the example file.

$ cp example.ini my_config.ini
$ vim my_config.ini

Kuha comes with a simple module for converting DDI Codebook files to unqualified Dublin Core. You can configure Kuha to use this module by settings the metadata_provider_class option to kuha.importer.ddi_file_provider:DdiFileProvider. The module needs two arguments: a domain name for the OAI identifier and a path of the directory to scan. Set these in the metadata_provider_args setting.

Example:

# my_config.ini

metadata_provider_class =
   kuha.importer.ddi_file_provider:DdiFileProvider

metadata_provider_args =
   my.organization.org
   /srv/metadata

# ...

See Extending for help on writing your own metadata provider.

Run the metadata import.

$ kuha_import my_config.ini

Start the OAI-PMH serverk

$ pserve my_config.ini

With the example configuration, you can get the identify page at http://127.0.0.1:6543/oai?verb=Identify.

For most applications, a custom metadata provider is needed. Metadata provider classes should implement an interface similar to kuha.importer.skeleton_provider:SkeletonProvider and kuha.importer.ddi_file_provider:DdiFileProvider. See comments in those files for details.

To make Kuha use your custom metadata provider, set the metadata_provider_class setting to the Python name of the class (e.g. name.of.the.module:NameOfTheClass). The value of the metadata_provider_args setting is split at whitespace and the resulting parts are passed to the constructor of the class.
