SEDRIS Standards         

The SEDRIS Organization works in cooperation with the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) Joint Technical Committee 1 (ISO/IEC JTC 1) to maintain the jointly developed set of International Standards based on the SEDRIS technologies.

The SEDRIS technologies have been assembled into the specifications and associated language bindings shown in the table below. Provided in the subsequent table is the SEDRIS standards development schedule.

Please send your feedback to: se-scrccb@sedris.org. We would like to hear about your experiences using these standards.

    Status
  • SEDRIS Standards Development
  • ISO/IEC 18023-1, 18025 and 18026 allow new concepts to be specified by the registration of new entries to these standards. New entries to the standards are registered using the established procedures of the International Register of Items.

    Information technology - SEDRIS - Part 1: Functional specification

      ISO/IEC 18023-1 defines the syntax, semantics and structure for the representation and interchange of environmental data, along with the means to produce and access that data.

    Information technology - SEDRIS - Part 3: Transmittal format binary encoding

      ISO/IEC 18023-3 defines a binary encoding technique that allows encoding DRM objects specified in ISO/IEC 18023-1 according to the abstract syntax specified in ISO/IEC 18023-2. The name of this binary encoding is SEDRIS Transmittal Format (STF).

    Information technology - SEDRIS language bindings - Part 4: C

      Access to the information stored in a SEDRIS transmittal is through an API. The abstract specification for this API is defined in ISO/IEC 18023-1. Each part of ISO/IEC 18024 defines the binding of that abstract specification to a particular programming language. ISO/IEC 18024-4 defines a standard binding for the C programming language.

    Information technology - Environmental Data Coding Specification (EDCS)

      ISO/IEC 18025 provides mechanisms to unambiguously specify objects used to model environmental concepts. A functional interface is also specified.

      NOTE:   The current content of the EDCS Registry is based on the standard when it was originally published in 2005, and the items added through Registration since then.  The EDCS Registry is in the process of being updated to reflect the new content of EDCS Edition 2, as well as to add an improved user interface, and will be available in the near future.

    Information technology - Spatial Reference Model (SRM)

      ISO/IEC 18026 defines relevant aspects of spatial positioning and related information processing. It allows precise and unambiguous specification of geometric properties such as positions (locations), directions, distances, and times associated with spatial information.

    Information technology - EDCS language bindings - Part 4: C

      Access to the codes defined by ISO/IEC 18025 is through an API. The abstract specification for this API is defined in ISO/IEC 18025. Each part of ISO/IEC 18041 defines the binding of that abstract specification to a particular programming language. ISO/IEC 18041-4 defines a standard binding for the C programming language.

    SEDRIS STANDARDS DEVELOPMENT

    Work on the SEDRIS family of standards began in 1998, in cooperation with ISO/IEC JTC 1/SC 24 under Working Group 8.
