The structOntology module is a separate conStruct module. This module has these main functions:

• To provide a user interface and framework within Drupal for updating and expanding the existing ontologies used by the system
• To allow mappings to external ontologies to be specified, and
• To enable simple export of the ontology structures from conStruct.

As noted below, ontologies are the basis for "data driving the application" and therefore have a central importance.

For ontologies within conStruct, structOntology enables these types of updates and expansions:

• Human-readable labels
• Alternative labels
• Readable descriptions
• Relationships between things and concepts.

structOntology is an important complement to conStruct because ontologies play these roles within the system:

• Conceptual Relationships
• Integrating Instance Data
• Orienting to Other Knowledge and Domains
• Mapping to Other Schema
• Linked Data, with Federated and Comprehensive Data
• Context- and Instance-sensitive Data Display
• Driving User Interfaces
  • Attribute labels and tooltips
  • Navigation and browsing structures and trees
  • Menu structures
  • Auto-completion of entered data
  • Contextual dropdown list choices
  • Spell checkers
  • Online help systems
  • Etc.

There is a YouTube video providing an demo of the system.
