Quick Start to Install ESMA ESEF Validation and Rendering

Several alternative installation strategies can be followed:

  1. Install a pre-built application.  These are available for release 16.2 with embedded Python and require no developer skills.
  2. Install from sources on gitHub. (See ESMA ESEF Technical Operation)

Once installed there are two strategies for using the ESEF validation and renderer:

  1. Interactively from its GUI.  (This now includes a local viewer using the same components as the sec.gov website.)
  2. Technical Operation: from command line, as a web service, or polled operation as a daemon service. (See ESMA ESEF Technical Operation)

Parameters can be specified by menu Tools->Formula Parameters.

The parameter, eps_threshold, is used as a formula tolerance (e.g. 1.00, .01, etc)

The parameter, authority, is used to specify an authority for validations in file plugin/validate/ESEF/resoources/authority-validations.json.  For example:

authority DK specifies Denmark features in the above json file.

authority GB specifies Great Britain ESEF features

authority UKFRC specifies UKSEF features (for submission to UK FRC vs ESMA).
