Geolinking Service	0.9.1	04-011r1	Peter Schut	2004-05-04
A Geolinking Service takes attribute data which refers to spatial features, and joins it to a geospatial dataset, so that it can be mapped by a WMS or used in a GIS. When a Geolinking Service uses data from a GDAS, and serves as a front end to a WMS, it enables real-time mapping of data stored in non-spatial databases.

Geospatial Semantic Web Interoperabiltiy Experiment Report	0.5.0	06-002r1	Joshua Lieberman	2006-08-21
The Semantic Web seeks to make the meaning as accessible as the material, by enabling connections - which are both logical and (machine) actionable - between concepts which a user presently understands and those which may be new and foreign. The Geospatial Semantic Web extends this capability to both content and concepts that are specifically spatial, temporal, and geographic in nature, giving both people and machines true access to a wider range of knowledge.
Geo Video Web Service	0.0.9	05-115	Joe Lewis	2006-03-28

Imagery Metadata	1.0	05-015	Barry Schlesinger	2005-01-27
Special XML schemas have been created for individual data sets, based on ISO 19115 and a general schema for the RSE. However, a generalized metadata XML schema should be available where possible; it should not be necessary to create special schemas for each data set. ISO 19139 can serve as such a general XML implementation specification for 19115. This implementation needs to be tested in practice. In addition, the new ISO standards are incorporating much, if not all, of the metadata not in 19115 that the RSE contain. XML schemas for these metadata need to be developed that are based upon the abstract model in the ISO standards. All of these implementations need to be tested in practice. This Report describes such tests and the results. It also describes to what extent metadata on which the test metadata are based are supported by 19139, to what extent they are supported by metadata specified in the new ISO standards or the RSE, and to what extent new metadata elements are needed.

OpenGIS Tiled WMS Discussion Paper	0.3.0	07-057r2	Keith Pomakis	2007-10-10
This OpenGIS Discussion paper describes two basic operations as proposed extensions to the WMS specification. The DescribeTiles operation provides the client with a description (i.e, the available layers, styles, image formats, coordinate systems, scales, sizes and locations) of the image tiles that are available to be requested from the server. The GetTile operation provides the client with the ability to request a particular tile. The difference between the standard GetMap operation and the proposed GetTile operation is fundamentally one of flexibility versus scalability.

OWS Messaging Framework	0.0.3	03-029	Stephane Fellah, Steven Keens	2003-01-20
This document defines a messaging framework to conduct communications between the OGC web services. It is independent of any transport protocol and any messaging encoding. By using the framework, the service designer could focus only on the message definitions and messaging flows for every action supported by the service, without worry on the messaging transport and delivery. The framework should considerably simplify the implementations of the OGC web services and should enable service chaining.
