| - <em><a href="#ontology">ontologies<a/></em> to describe the conceptual |
| - aspects of structured <em><a href="#resource">resources</a></em>, |
| - e.g., information sources such as data sets and services (workflows, |
| - actors, and web-services). Each resource is assumed to have a well |
| - defined schema that describes the structure of associated data (in the |
| - case of services, e.g., inputs and outputs). In addition to providing |
| - metadata for resources, ontology-based semantic annotations can enable |
| - improved discovery and integration of data. |
| - |
| - <p> Properly describing the semantics of a resource often requires |
| - "fine-grain" annotation, in which different parts of the resource are |
| - annotated with distinct semantic information, possibly including the |
| - assertion of semantic relations among the parts. The challenge is to |
| - provide an appropriate language for accessing, annotating, and |
| - relating portions of resources. This technical note describes basic |
| - aspects of <em><a href="#template">semantic annotation |
| - templates</a></em>, which are designed to support these fine-grain |
| - resource annotations. |
