9.2.2 WPS for Fusion
Based on the results documented in Feature and Statistical Analysis ER OGC 10-074 and WPS Profiling ER OGC 10-059, these recommendations relevant to Fusion
Standards Study are noted:
• WPS profiles are needed in order to achieve semantic interoperability of
Geoprocessing. Grouping of algorithms is needed. The FAS ER identified hierarchies and classifications such as “Topology Analysis” and “Statistical
Analysis”.
• Designing WPS Profiles is a challenge not only regarding choosing the
appropriate input and output type definitions, but also regarding choosing appropriate classifications. For this reason, a holistic approach is required to
reflect the complexity of appropriate process design.
• Metadata profiles for registering WPS in OGC Catalogs are missing and hinder
the use of the publish-find-bind pattern. Future work should consider the prior development of WPS Profiles in OWS-5 regarding
Conflation Rules. Further consideration of the rules approaches identified in OWS-5 should be considered. OGC Document 07-160r1 from OWS-5 made this statement:
• One possible approach to implementing rules as services would be to use the
OGC WPS standard with the various conflation rules processes defined, for example, as GetRuleX, SetRuleY, etc. The DescribeProcess would describe the
44 Copyright © 2010 Open Geospatial Consortium inputs needed to retrieve the Rule as well as a description of the rule and its
assumptions.
9.2.3 Authoritative Data Source Directory
A key part of supporting feature and decision fusion are catalog, or registry services, providing sophisticated capabilities to discover, organize and access relevant data
sources. One currently popular term for this kind of information service is an Authoritative Data Source.
An Authoritative Data Source Directory ADSD was investigated in the OWS-7 FDF Thread OGC 10-086. ADSD is a resource capable of organizing and discovering a
wide variety of types of data such as web sites, books, picturesimages, et al. as well as available web services. The directory is to have the ability to identify and query for data
sources based on socio-cultural themes, geographic area either coordinates or geographic name, temporal relevance, and data quality e.g. precision, fitness for use. The ADSD
concept was implemented as an OGC Catalog Service supporting all interfaces of CSW 2.0.2 plus extensions developed to support ADSD. OpenSearch was adopted as a
metaphor for the extensions.
