# Degree of Establishment Controlled Vocabulary List of Terms Title : Degree of Establishment Controlled Vocabulary List of Terms Namespace URI : Preferred namespace abbreviation : dwcdoe: Date version issued : 2021-09-01 Date created : 2020-10-13 Part of TDWG Standard : This document version : Latest version of document : Previous version : Abstract : The Darwin Core term `degreeOfEstablishment` provides information about degree to which an Organism survives, reproduces, and expands its range at the given place and time.. The Degree of Establishment Controlled Vocabulary provides terms that should be used as values for `dwc:degreeOfEstablishment` and `dwciri:degreeOfEstablishment`.

Wilson, Paula F Zermoglio, Annie Simpson Creator : TDWG Darwin Core Maintenance Group Bibliographic citation : Darwin Core Maintenance Group. 2021. Degree of Establishment Controlled Vocabulary List of Terms. Biodiversity Information Standards (TDWG). ## 1 Introduction This document includes terms intended to be used as a controlled value for Darwin Core terms with local name `degreeOfEstablishment`. For details and rationale, see Groom et al. 2019. Improving Darwin Core for research and management of alien species. ### 1.1 Status of the content of this document In Section 4, the values of the `Term IRI`, `Definition`, and `Controlled value` are normative. The value of `Usage` (if it exists for a given term) is normative. The values of `Term Name` are non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace. `Label` and the values of all other properties (such as `Notes`) are non-normative. ### 1.2 RFC 2119 key words The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119](https://tools.ietf.org/html/rfc2119). ## 2 Use of Terms Due to the requirements of [Section 1.4.3 of the Darwin Core RDF Guide](http://rs.tdwg.org/dwc/terms/guides/rdf/#143-use-of-darwin-core-terms-in-rdf-normative), term IRIs MUST be used as values of `dwciri:degreeOfEstablishment`. Controlled value strings MUST be used as values of `dwc:degreeOfEstablishment`. ## 3 Term index [captive (category B1)](#dwcdoe_d002) | [casual (category C1)](#dwcdoe_d006) | [colonising (category D1)](#dwcdoe_d009) | [cultivated (category B2)](#dwcdoe_d003) | [degreeOfEstablishment concept scheme](#dwcdoe_d) | [established (category C3)](#dwcdoe_d008) | [failing (category C0)](#dwcdoe_d005) | [invasive (category D2)](#dwcdoe_d010) | [native (category A)](#dwcdoe_d001) | [released (category B3)](#dwcdoe_d004) | [reproducing (category C2)](#dwcdoe_d007) | [widespread invasive (category E)](#dwcdoe_d011) ## 4 Vocabulary
