Abstract

Hydra terms extensively described with Shapes Constraint Language (SHACL).

1. Introduction

This extensions describes Hydra Core Vocabulary terms using Shapes Constraint Language (SHACL). It neither present any new Hydra terms nor replaces any existing definitions. It SHOULD be used in conjunction with the Hydra Core Vocabulary specification as it is a complementary specification.

It’s purpose is purely to describe all the terms with pure Resource Description Framework Schema (RDFS) and Shapes Constraint Language (SHACL) vocabulary so is is possible to validate hydra constructs.

Conformance

Conformance requirements are expressed with a combination of descriptive assertions and RFC 2119 terminology. The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in the normative parts of this document are to be interpreted as described in RFC 2119. However, for readability, these words do not appear in all uppercase letters in this specification.

All of the text of this specification is normative except sections explicitly marked as non-normative, examples, and notes. [RFC2119]

Examples in this specification are introduced with the words “for example” or are set apart from the normative text with class="example", like this:

This is an example of an informative example.

Informative notes begin with the word “Note” and are set apart from the normative text with class="note", like this:

Note, this is an informative note.
