Composite Resource

Introduction

Composite resources provide the ability to group together multiple files of different types in one resource, such as:

  • Shapefiles representing a watershed boundary (polygon), observation sites (points), and time series and reference time series representing observations made at the observation sites.
  • Shapefiles, log files, and grid files from a Watershed Analysis.
  • Model instance files, where files that are part of a model instance need to be specifically typed

 A composite resource is:

  • Managed as one discoverable resource
  • Contains one set of access controls (Owners, Editors, private or public, etc.)
  • Has one unique identifier
  • Has one set of resource level metadata (authors, contributors, spatial and temporal coverage etc.)
  • Can have metadata specific to each file or content aggregation within it

HydroShare supports data Content Types within composite resources that collectively comprise core data types widely used in Hydrology.  In addition any type of file can be added to a HydroShare resource and, if desired, have single file metadata associated with it. For many of the content types, several files are required. For instance, when a user adds a shapefile to the composite resource, they must add at least the following three shapefile component files:  .dbf, .shp, .shx. Content types comprised of multiple files are placed in a folder with symbol indicating the content type. Individual member files can be accessed by opening the content type folder.
