You purchase a license for ECLASS Release 11.1 all available languages and all export formats: BASIC (csv and XML) and ADVANCED (XML). ECLASS 11.1 has been published on 2020-08-10.


Update 2021-10-18: BASIC and Advanced XML were re-exported due to two incorrect entries in the XML dictionaries in the tags <revision> and <label>. Some ECLASS users use the <revision> tag to be able to identify if an ECLASS version is newer than or equivalent to the already loaded schemas. Furthermore, the <label> tag indicated the old spelling of the word ECLASS.

IMPORTANT: There was no change to the ECLASS content.

<revision> entry of the replaced file      "...XML01": 11.0.1
<revision> entry of the re-exported file "...XML02": 11.1

<label> entry of the replaced file      "...XML01": eCl@ss11.1
<label> entry of the re-exported file "...XML02": ECLASS11.1


Most of the language versions are partly translated; the rest filled with the English original.

The ECLASS Minor Release 11.1 is an enhancement and modification of the ECLASS Major Release 11.0. With Release 7.0 an improved structure according to the underlying ISO13584 data model and an ISO-standard XML format (OntoML) was introduced.

Starting with ECLASS Release 7.0, there are two different versions of ECLASS which contain the same classes, but differ in the product description on the basis of properties and values:

  • BASIC (in .csv or .XML format). The BASIC version contains only the content that could be represented in a .csv format that was the exclusively used export format before 7.0. Therefore, it does not contain property block structures nor dynamic elements as in the ADVANCED version. BASIC does contain all classes of the ADVANCED, but the product description with the help of properties and values is structured a lot easier. BASIC is therefore a subset of ADVANCED.
  • ADVANCED (only in .XML format). The ADVANCED version is the leading version in the database and built on the basis of the data model ISO13584. It contains all structural elements of the ECLASS classification system including property blocks, dynamic elements such as reference properties, polymorphism and cardinality blocks. The description of these extended structural components as well as additional meaningful information can be found here:
    Each classification class refers to both an ADVANCED and a BASIC application class that contains the product description with the help of properties and values. The ADVANCED version contains the complete content of ECLASS and is therefore an extension of the BASIC version.
    Under you may find an overview (matrix of functionalities) which makes it possible for you to compare the two versions (BASIC and ADVANCED) and their possibilities. A provided reference table (XML File: Mapping BASIC_ADVANCED) enables users of the ADVANCED version to exchange technical data with users of the BASIC version. Hereby, the necessary know-how has to be delivered by the user of the ADVANCED version.

ECLASS 11.1 comprises in comparison to Release 11.0:

  • ca. 850 new classes
  • ca. 60 new blocks
  • ca. 300 new properties
  • ca. 2,150 new values
  • ca. 16,600 new property and value assignments

All available downloads at the ECLASS DownloadPortal generally contain a complete ECLASS version in csv format or XML format (for initial implementation). For information on the data structure, please refer to the enclosed README file.

The content has been extensively expanded, particularly in the following segments:

  • 23 "Machine element, fixing, mounting"
    • Enhancements on keyword level and introduction of the topic UFI code
  • 27 "Electric engineering, automation, process control engineering"
    • Ongoing content development and content harmonization with the standard ETIM
  • 29 "Home economics, Home technology"
    • Ongoing content harmonization with the standard APPLiA PI
  • 33 "Installation (complete)"
    • Introduction of new classes for the sector "wind energy"
  • 50 "Interior furnishing"
    • Ongoing content development and introduction of blocks
  • 51 "Fluid power"
    • Ongoing content development and introduction of important ISO properties

 Content ECLASS 11.1 BASIC (csv):

  • Classes file (complete)
  • Properties file (complete)
  • Keywords and Synonyms file
  • Values file (complete)
  • Unit file (complete)
  • Class-Property relations file
  • Value lists (restricted Property-Value relations file, only BOOLEAN properties)
  • Proposal lists (suggested Class-Property-Value relations file incl. constraints)
  • README file ECLASS standard


  • Dictionaries: include 39 XML files, hence for each segment one XML file that contains the complete content of the relevant segment (Classes, Keywords, Properties, Synonyms, Values, Value Lists, Units and all relations) (complete)
  • Templates: Since Release 10.0.1, the "Templates" folder already known from previous Releases does not contain any content. The reason for this is the future handling with templates to deliver and publish only "default" templates with substantial content. This may change for future Releases.
    Templates contain a Data Requirement Statement for the data exchange, in which can be defined e.g. sequences or optional and mandatory fields between the data transmitter and the receiver. More information in the ECLASS Wiki:
  • ECLASS units ("UnitsML" in XML format)
  • Only ADVANCED: Additionally for the ADVANCED user the mapping file BASIC - ADVANCED is included
  • README file

In the following you will find the structure of the XML files.

The placeholder "xy" stands for the different language codes. An explanation of the language codes can be found in the ECLASS WIKI:
