Official and Complementary Publications Explained

Below is a diagram that represents the Official Portfolio and the wider complementary portfolio. Click the image to view each category:

The Official Portfolio includes:

• The OGC required products (shown in green). These are the OGC Core reference material and a range of derived products. All products that are OGC-required are "Crown copyright – value-added".
• Complementary material from the Official Publisher, Official Accreditor and web based complementary products.

The Wider Complementary Portfolio includes third party complementary products which use an OGC trade mark. These have been quality reviewed to ensure compliance of the material with the brand principles.

The nature of the OGC core products is such that they need to be interpreted and adapted for use. As a result of feedback from the marketplace, OGC-required products include all Core products and a restricted set of derived products. These derived products include introductions to the framework(s), specific pocketbooks covering key elements of the core framework and study guides in support of the emerging qualifications.

Listings of individuals and organisations that hold active OPSI licenses, whose material is incorporated within the wider complementary portfolio, can be found on OPSI's licensees list.
