eduGAIN Credential Conversion Service (''eCCS'')
=== eduGAIN Credential Conversion Service (''eCCS'') ===
Defining rules for attribute transformation has come up in different areas. Shibboleth uses <code>*AttributeDefinition</code> elements to define conversion rules from data source (e.g LDAP) attributes to released attributes. However the most closely related work is a paper from Gabriel López et al. called describe a common [[Media: eccs.pdf | 'eduGAIN Credential Conversions Service']].
==== Summary ====
They propose a central (although technically distributable) service for carrying out attribute conversion to and from a common representation (eduGain Common Credentials, ''eCC''). Conversion polices for converting local attributes to ''eCC'' and vice versa are included in the metadata. Attributes can be transferred between BEs in ''eCC'' representation and in 'source format' (in unconverted form). In both cases an RBE needs to invoke ''eCCS'', which sends back attributes in the required format of the remote federation.
