General Description:

This course is given in English as it corresponds to a Teaching Unit of the International MSc on Cyber Physical and Social Systems (CPS2): AI and IoT

This lecture aims at understanding the data interoperability issues that arise from the integration of existing application, or the evolution of systems. The students will understand and use the main data formats, query languages, and schema definition languages. They will understand the importance of controlled vocabularies and ontologies, and the importance of relaxing data schemas to enable the injection of additional information in documents. The course combines theory and practice on the following topics:

  • Generalities: data engineering and the data value chain, ISO/IEC definitions of interoperability, standards and standard-based interoperability
  • Encoding base data types: character encoding,  Computer number formats, Colors, Endianness,  Base32 and Base64 encoding, 
  • Data formats: Generalities, file types, Delimiter separated values, Extensible Markup Language, JavaScript Object Notation, YAML Ain't Markup Language,  Lightweight markup languages,  Compressed formats, Multimedia formats
  • Data schemas and semantics: XML Schema, JSON Schema, Heterogeneities and data conflicts, Controlled vocabularies and ontologies, Resource Description Framework, RDFa: Rich structured data markup for web documents, JSON-LD: JSON for Linking Data, Data integration and mediation

Key words:
