IGeoDataset Provides access to members that provide information about a Geographic Dataset.
IMetadata Provides access to members that manage and update metadata.
IMetadataEdit Provides access to members that provide information about whether metadata can be edited.
ISchemaLock Provides access to members for accessing schema locking functionality.

ITopologyRuleContainer Provides access to members that return and set topology rules.

Remarks

A Topology is a collection of simple feature classes within the same feature dataset that participate in topological relationships with a set of rules that govern those relationships.  The Topology object is not cocreateable, topologies must be created through another method call, ITopologyContainer::CreateTopology.

Topologies support the IFeatureClassContainer interface that can be used to return the feature classes participating in the topology. Among other interfaces, Topologies also support IDataset.

Each topology has one inherent rule, esriTRTFeatureLargerThanClusterTolerance, which identified features that are less than the defined cluster tolerance for the topology.
