OGC: Automated Compliance Tests

The OGC Announces New Automated Compliance Tests

Wayland, MA, USA. June 26, 2007.

The Open Geospatial Consortium, Inc. (OGC) membership has adopted new test suites, test scripts and reference implementations for OpenGIS Specifications. A new TEAM Engine (Test, Evaluation, and Measurement Engine) and Compliance Test Language were adopted as the OGC's official new compliance testing platform.

These new free tests and testing software enable technology providers to confirm that their products are compliant with OpenGIS standards. Providers can then submit products for certification. Certified products can carry the OGC "Certified Compliant" mark to formally signify adherence to OGC standards.

Test suites were adopted for the following OpenGIS implementation specifications:

  • Web Map Service (WMS) 1.3.0
  • Web Feature Service (WFS) with Filter Encoding 1.1.0
  • Geography Markup Language (GML) Simple Features SF 1.0
  • Catalog Services - Web (CS/W) 2.0.1
  • Web Map Context (WMC) 1.1.0
  • GeoRSS GML

To assist programmers in developing solutions, open source reference implementations were adopted for:

  • WMS 1.3.0
  • CS/W 2.0.1
  • WFS 1.1.0

Developers can download the TEAM Engine from to test their implementations of the OGC's OpenGIS implementation specifications in the developers' own environments.

The TEAM Engine, an open source program developed by Northrop Grumman, and the test suites and reference implementations, contributed by other OGC members, were among the results of the OGC's fourth OGC Web Services test bed activity (OWS-4).

Official OGC Compliance Testing, available only at can be done online for a compliance report and/or for submission of a product or service for certification and OGC Compliance branding. This site provides more information about the test suites. More information about the OGC Compliance Testing Program and trademark licensing is available at

The OGC is an international industry consortium of more than 335 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available interface specifications. OpenGIS Specifications support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. The specifications empower technology developers to make complex spatial information and services accessible and useful with all kinds of applications. Visit the OGC website at:

About OGC Compliance and Interoperability Testing & Evaluation (CITE) Initiative

"The OGC Compliance & Interoperability Testing & Evaluation (CITE) Initiative is an ongoing initiative of the OGC that is building tests for OGC specifications. CITE-1, the first in the series, developed a planning and feasibility study that helped to refine the existing Compliance Testing Program. CITE-1 developed a scriptable compliance testing engine and tests for WMS 1.1.1 and WFS 1.0.0, as well as a validation capability for GML 2.1.2. The CITE-1 initiative also developed reference implementations for WMS and WFS and this important portal resource. OWS-2 developed a compliance test suite and reference implementation for WCS 1.0.0.

OWS-4 integrated a new open source engine that can be run from the command line or web interface, developed a new Compliance Test Language (CTL), migrated the existing WFS 1.0 and WMS 1.1.1 test suites to the new engine, and developed new test suites for CSW 2.0.1, WFS 1.1, WMS 1.3. In addition, the new engine will validate Web Map Context (WMC 1.1.0) instance documents. A GeoRSS feed validator was also created during this timeframe.

CITE-related work may occur within other Interoperability Initiatives (such as OWS-5) or may also occur in focused initatives in the future. CITE-related work can also be accomplished completely outside of initiatives and, in fact, OGC strongly encourages those who are able to do just that — we only ask that you notify us of your intent so that we can coordinate these activities to avoid redundant or conflicting work..."
