Class: Thing

The most basic, identifiable item. In addition to the slots that are common between a Thing and an AttributeSpecification (see ThingMixin), two additional slots are provided. The id slot takes the required identifier for a Thing. The relation slot allows for the inline specification of other Thing instances. Such a relation is unqualified (and symmetric), and should be further characterized via a Statement (see characterized_by). From a schema perspective, the relation slots allows for building self-contained, structured documents (e.g., a JSON object) with arbitrarily complex information on a Thing.

description: "Large-scale datasets present unique opportunities to perform scientific investigations with unprecedented breadth. However, they also pose considerable challenges for the findability, accessibility, interoperability, and reusability (FAIR) of research outcomes due to infrastructure limitations, data usage constraints, or software license restrictions. Here we introduce a DataLad-based, domain-agnostic framework suitable for reproducible data processing in compliance with open science mandates. The framework attempts to minimize platform idiosyncrasies and performance-related complexities. It affords the capture of machine-actionable computational provenance records that can be used to retrace and verify the origins of research outcomes, as well as be re-executed independent of the original computing infrastructure. We demonstrate the framework’s performance using two showcases: one highlighting data sharing and transparency (using the studyforrest.org dataset) and another highlighting scalability (using the largest public brain imaging dataset available: the UK Biobank dataset)."

      determined from some descriptor (e.g. a quantity, position, label/identifier).
      Technically, this declaration is done via an `AttributeSpecification` that combines
      a `predicate` with a value declaration and the attribute-related slots of a
      `Thing`. Importantly, such attributes are declared inline, because they do not
      have a unique identifier. If an identifier is available, a `Thing` declaration
      (see `relation`), and a qualification of that relationship via a `Statement`
      (see `characterized_by`) should be preferred.
