Reference data for SMEs

Description of the course

The course explains the use of standard reference data on the Web.

Different types of reference data are described, including:

  • vocabularies of generic terms (e.g. "part of", "made of", "model");
  • catalogues of standard parts provided by manufacturers or suppliers;
  • dictionaries of materials and chemicals (e.g. as identified by a CAS registry number)
  • vocabularies of generic object types (e.g. "tank", "pipe", "valve");
  • dictionaries of property types (e.g. "mass when empty", "supply voltage".

Sources of reference data are described and the way to make computer interpretable reference.


  1. Types of reference data: an overview of the types of reference data (vocabularies, catalogues and dictionaries), and how they are used

  2. Sources for reference data: a description of reference data defined by international standards (e.g. ISO 15926 "Lifecycle data for process plant", ISO 14048 "Life cycle assessment", ISO 13584 "Parts libraries"); by trade associations (e.g CAS registry); and by suppliers

  3. A case study: a demonstration of the RDL (Reference Data Library) server provided by the POSC-CAESAR Association for the reference data in ISO 15926-4.
