A repository for collaboration on a glossary of digital twins and digital twin technology from the Digital Twin Consortium.
Sometimes less is more. Some relevant questions to ask about a candidate term include:
- Does the term add value in the form of clarification or context that is not available in a common dictionary?
- Does the term provide a place to reference other DTC-defined content?
- Does the term solve a terminology problem for the author of a digital twin use case or some other product of the DTC?
- Is the term industry-specific?
- The glossary is not intended to cover industry-specific domains for which one might build a digital twin system.
- For example “bridge abutment”, “rotator cuff”, “supply chain”, “financial asset”, etc. probably belong in a different glossary.
- Is the term implementation-specific?
- This glossary is not the place to describe the terms of a particular implementation approach.
- We may have entries for types of technology relevant to digital twins, and those entries may list (and link to) specific examples.
- Does the definition apply across all industry domains?
- Is the term really necessary? What problems would be caused if it were omitted?
Before submitting new entries, author's should first reference: Github's Contributor Guidelines.
Only the formal definition following the template > A {term} is a {broader term} that {differentiating clause}. is required--other content is optional.

Alternate terms

- {non-term} {Explanation of why it is not preferred}
Narrower terms
- [{narrower term 1}(#narrower-term-1)]

### Formal Definition
The formal definition should be a complete sentence following the template
`> A {term} is a [{broader term}](#broader-term) that {differentiating clause}.`
For example
`> A kangaroo is a marsupial that lives in Australia, hops, and is a good boxer.`
(but create a hyperlink to "marsupial" if it is defined elsewhere in the glossary.)
### Context
This section includes elaboration, examples, counter-examples, motivations, pictures and clarifies the meaning and usage of the term.
### Alternate Terms
These can use complete sentences to indicate if the alternate term is non-preferred or to explain the context in which the synonym is commonly used. If there is an entry for the alternate term, link to it.
### Narrower Terms
These are hyperlinks to entries "lower" in the taxonomic hierarchy. For example, the entry for "kangaroo" might list the "narrower" terms: "red kangaroo", "eastern grey kangaroo", "western grey kangaroo", and "antilopine kangaroo".
### Related Terms
These should be complete sentences that describe how the {term} relates to some other term. For example:
```markdown
- A digital twin is implemented in a [digital twin system](#digital-twin-system).
- A digital twin has a corresponding [physical twin](#physical-twin).
- A digital twin is part of a [cyber-physical system](#cyber-physical-system).
You may include entries for non-terms or synonyms simply as a place to link back to the primary entry.
## {Non-Preferred Term}
Use [{term}(#term)] instead.
