Here there are the slides of the SALTED project presented at the session on SDM during past FIWARE summit held at Vienna.

It deals with data enrichment and how to merge heterogeneous data sources.

FIWARE summit presentations. Training on SDM.

In these links you can find the two presentations of the training camp held during past week FIWARE summit.

New data model DataServiceRun. Candidate for extending DCAT-AP

  By

The new data model, DataServiceRun, is included into the Smart Data Models’ subject DCAT-AP. Initially this subject maps all the contents of the standard DCAT-AP 2.0.1 but also, aligned with the agile standardization philosophy of the initiative, it extends exiting data models and hopefully would be submitted to the original standardization group for its adoption.

Also the data model DataService has also been extended with 3 additional attributes.

DataServiceRun. A representation of one specific run of a data service (e.g. DataService).

New test service for contributors. Strongly recommended before contributing a data model.

  By

There is a new service for simplifying the testing of a contribution to a data model.

The new service will check it, just by providing the link to the root of the folder in an publicly accessible repository

  • That the schema.json is
    • Present in the right position
    • It is a valid json and it has the right structure (types and descriptions)
    • It has the right metadata, and the required section
    • External references are valid
    • The descriptions are included
  • That the examples are:
    • Present in the right position
    • Key values are validated by the schema
  • Notes.yaml and ADOPTERS.yaml are present in the right position

all the files (mandatory ones like schema and examples) and the optional (notes.yaml, ADOPTERS.yaml)

There is a specific page for this test in the contribution manual

Subject Saref for systems and 3 DM, Connection, ConnectionPoint and System

  By

The new subject datamodel.S4SYST is mapping the data models from SAREF for systems 1.1.2.

Thanks to the contributors Grzegorz Wiszniewski and Jakob Bjørnskov t the project Twin4Build – A holistic Digital Twin platform for decision-making support over the whole building life cycle.

  • Connection. The class of connections between systems. This class qualifies property s4syst:connectedTo. A connection describes potential interactions between systems. Any two connected systems are connected through a connection. A connection can connect more than two systems at the same time.

  • ConnectionPoint. The class of connection points of systems, at which they may be connected to other systems. This class qualifies properties s4syst:connectsSystem and s4syst:connectedThrough. A connection point belongs to exactly one system. Any system connected through a connection is connected at one of its connection points to the connection. The system of a connection point that is connected through a connection is itself connected through the connection.

  • System. The class of systems, i.e., systems virtually isolated from the environment, whose behaviour and interactions with the environment are modeled. Systems can be connected to other systems. Connected systems interact in some ways. Systems can also have subsystems. Properties of subsystems somehow contribute to the properties of the supersystem.
