Cataloguing Earth Observation Products for ebXML Registry Information Model 3.0 based Catalogues  1.0  10-189r2  Frédéric Houbie; Fabian Skivee 2012-06-12
This OGC® document specifies the Earth Observation Products Extension Package for ebXML Registry Information Model 3.0, based on the [OGC 10-157r1] Earth Observation Metadata profile of Observations and Measurements. It enables CSW-ebRIM catalogues to handle a variety of metadata pertaining to earth observation p/roducts as defined in [OGC 10-157r1]. This proposed application profile document describes model and encodings required to discover, search and present metadata from catalogues of Earth Observation products. The profile presents a minimum specification for catalogue interoperability within the EO domain, with extensions for specific classes of metadata.

Definition identifier URNs in OGC namespace  1.3  07-092r3  Arliss Whiteside 2009-01-15
This document specifies Universal Resource Names (URNs) in the “ogc” URN namespace to be used for identifying definitions. These definitions include definitions of Coordinate Reference Systems (CRSs) and related objects, as specified in OGC Abstract Specification Topic 2: Spatial referencing by coordinates, plus several other resource types for which standard identifiers are useful in OGC Web Services. This document specifies the formats used by these URNs, including formats that can reference definitions recorded in the EPSG database and by other authorities. This document also specifies URNs for some specific definitions for which OGC is the custodian.

Gazetteer Service - Application Profile of the Web Feature Service Best Practice  1.0  11-122r1  Panagiotis (Peter) A. Vretanos, Jeff Harrison 2012-02-17
This document defines a Gazetteer Service profile of the OGC Web Feature Service Standard. The OGC Gazetteer Service allows a client to search and retrieve elements of a georeferenced vocabulary of well-known place-names. This profile extends the WFS interface in a way that a client is able to – Determine if a WFS implementation is acting as a Gazetteer Service. – Query the Gazetteer Service in order to retrieve place-name features without closer examination of the feature type definitions – Access metadata about the gazetteer(s) provided by the service – Update place-name features using WFS transactions – Fetch place-name features that have Parent-Child relationships and then follow those links

It specifies how to create the necessary PDF objects that identify a region of the PDF page as a map and describe the map’s coordinate systems. Map creation and rendering to a PDF page are not addressed. The underlying PDF file format is not addressed. The file format is specified in PDF Reference[1] .
Reference Model for the ORCHESTRA Architecture  2.1  07-097  Thomas Uslander (Ed.) 2007-10-05
This document specifies the Reference Model for the ORCHESTRA Architecture (RM-OA). It is an extension of the OGC Reference Model and contains a specification framework for the design of geospatial service-oriented architectures and service networks. The RM-OA comprises the generic aspects of service-oriented architectures, i.e., those aspects that are independent of the risk management domain and thus applicable to other application domains.
Semantic annotations in OGC standards  2.0  08-167r2  Frédéric Houbie, Philippe Duchesne, Patrick Maué 2012-10-10
In this OGC Best Practice, the concept of semantic annotations is introduced. Annotation of Web Services or data compliant to OGC standards refers to the task of attaching meaningful descriptions to the service and the served geospatial data or processes.
Sensor Alert Service  0.9  06-028r3  Ingo Simonis 2007-05-16

Summary of the Architecture, Engineering, Construction, Owner Operator Phase 1 (AECOO-1) Joint Testbed  0.3.0  10-003r1  Louis Hecht, Jr., Raj Singh 2010-06-04
The Architecture, Engineering, Construction, Owner Operator, Phase 1 (AECOO-1) Testbed developed and implemented methods to streamline communications between parties in the conceptual design phase to get an early understanding of the tradeoffs between construction cost and energy efficiency. To that end, the project developed the interoperability components required for these analyses in collaborative team settings. These were Information Delivery Manuals (IDMs) for quantity takeoffs and energy analysis business processes, and used these to define Model View Definitions (MVDs)—standards-based subsets of Industry Foundation Classes (IFCs). AECOO-1 was conducted in response the felt need that overall productivity loss and fragmentation in the capital facilities development industries is no longer tolerable. All stakeholders need to practice the best way they know, and practice profitably; software interoperability problems must not hold them back. Non-interoperable software and data is cause for loss of competition across the market.

Web Notification Service  0.0.9  06-095  Ingo Simonis, Johannes Echterhoff 2007-01-25
A service by which a client may conduct asynchronous dialogues (message interchanges) with one or more other services. This service is useful when many collaborating services are required to satisfy a client request, and/or when significant delays are involved is satisfying the request. This service was defined under OWS 1.2 in support of SPS operations. WNS has broad applicability in many such multi-service applications. It is now used in several SWE scenarios.
