InteroperAble Descriptions of Obervable Property Terminology WG (I-ADOPT WG)

I-ADOPT in a nutshell

Under the auspices of the Research Data Alliance (RDA) Vocabulary and Semantic Services Interest Group (VSSIG) a small number of semantic experts formed a task group in 2018 to address the interoperability of observational data. The group submitted a case statement to work on the development of a common method to systematically express or represent observable properties in May 2019.

The RDA WG I-ADOPT was officially launched in 2019 and has 131 members. The WG completed its 18-month workplan in 2021.

Find here all performed tasks and their outputs:

Task 1: Collect user stories and formalise them into use cases (November 2019 - February 2020)

Task 2: Survey existing observation-centric terminologies (January 2020 - February 2020)

Task 3: Derive use case requirements (March 2020 - April 2020)

Task 4: Analyse semantic representation of Observable Properties against requirements (May 2020 - October 2020)

Task 5: Develop the Interoperability Framework (November 2020 - April 2021)

Task 6: Test local mapping design patterns (May 2021 - September 2021)

The I-ADOPT recommendations were finalized in January 2022 and endorsed by RDA in April 2022 (DOI: 10.15497/RDA00071). The Working Group is in maintenance mode, but is still active in refining the I-ADOPT Framework and helping with its implementation. You can contribute to this Working Group by submitting your own variables, submitting your questions and working with us in our recurring meetings.

Main Outcomes

The I-ADOPT Framework Ontology is a lightweight ontology primarily designed to facilitate interoperability between existing variable description models (including ontologies, taxonomy, and structured controlled vocabularies).

In 2023 we extended the ontology to support the aggregation of variables using a range of user-defined coarser concepts to facilitate dataset discovery and aggregation into products.

The I-ADOPT Catalogue of Terminologies contains concepts from terminologies to compose semantic variable descriptions.

The Step-by-Step guide was created to support in the description of new variables.

An Example

Applying the I-ADOPT Framework means:

  1. decompose the variable in atomic components
  2. assign a description role for each component
  3. annotate each component with concepts from terminologies

This I-ADOPT decomposition and annotation exercise should result in a variable concept with its associated concepts in a SKOS vocabulary:
