ICM – Computer Science Major – Course unit on Interoperability of Data and Semantics and M1 Cyber Physical and Social Systems – Course unit on System Modeling

Institut Henri Fayol - MINES Saint-Étienne

Syllabus

This lecture aims at ensuring you are familiar with data and information, at the core of every information technology (IT). The course focuses on four main topics:

  1. Encoding base data types. Numbers, characters, date and time, languages, quantities and units of measures, colors, etc.

  2. Data formats. Delimiter separated values, XML, JSON, YAML, data formats for configuration files, markup, multimedia, or 3D models.

  3. Data schemas and semantics. Covering XML and JSON schema, controlled vocabularies and ontologies, the Resource Description Framework, rich structured data.

  4. The value of data. Everything related to data storage and processing, the data value chain, open data, data interoperability.

  5. The European strategy for data. The regulatory framework Europe has put in place to boost the data economy, and a focus on data spaces.

You will practice with tutorials, and gain experience through practical work.
