Sequencing

The Sequencing OSID is an auxiliary service for sequencing Ids. Sequences may be externally applied to any OsidObject. An OsidObject may particpate in multiple sequences, or Chains, that can each be applied and accessed to different users or contexts.

Chains

A Chain is a set of Ids that can be sequenced.

Antimatroid Cataloging

Chains may be organized into federateable OsidCatalogs called Antimatroids.
