Meta-metadata for technical documentation in Industry 4.0
VDE SPEC 90009 V1.0 created with participation of EC Systems
What is metadata?
Metadata describe information products. In technical communication, metadata frequently includes validity, target groups, variants or content types. They can originate from various machine and/or manual sources and are managed and evaluated in various information systems (editorial systems, PIM systems, content delivery systems, etc.).
What is meta-metadata?
Meta metadata describe metadata, they make a statement, for example, about the origin of metadata or about their reliability.
An example: Metadata can be generated with AI methods. Given information products are analyzed automatically and the presumed metadata is derived from a number of different parameters. Reliability, i.e., the probability that the metadata has been correctly assigned, is one such meta-metadata and is important for the further use of the generated metadata.
Meta-metadata also includes statements about the actors involved in the creation of metadata (persons, organizations, SW systems), which may play a role in the use of the metadata.
The genesis of VDE SPEC 90009 V1.0
During the creation of the VDE SPEC, the project group ...
- ... collected the wishes and ideas by means of interviews with stakeholders from industry and SW development,
- defined the requirements for a meta-metadata model,
- developed the model ,
- implemented the model into a structure definition,
- mapped the exemplary implementation of the structure in JSON and XML and
- created the VDE SPEC and tuned it in an iterative process.
Application and benefits of the VDE SPEC
The use of standardized meta-metadata is helpful ...
- ... when generating metadata using AI methods and tools,
- when using information products in editorial systems, especially if their metadata comes from external sources, e.g. to better evaluate the quality of metadata,
- when exchanging information products and their metadata between different systems, e.g. transferring content created in the editorial system to a content delivery portal, or
- when evaluating metadata in information portals or other content delivery systems in order to improve search quality.
