Overview

A Namespace is used to define a set of local Identifiers. All identifiers within a Namespace must be unique. Namespaces are shared across projects. In TaxonWorks Identifiers + Namespaces are used for differentiating/disambiguating one datum from another. This applies to all local identifiers, not just what most might be familiar with in the DwC catalogNumber field.

Namespaces are used to to meet practical needs that also have FAIR consequences:

  • They attempt to provide a degree of provenance as to how the Identifier came to be

  • To differentiate, in practical terms, one identifier from another within the system that merges data

  • To act as a labels (short mneomincs) that allows the data curator to disambiguate what might be otherwise two identical strings

Namespaces are minted in TW on a first come first serve basis. Their short and long names must be unique. When conflicts arise new values must be minted for record keeping purposes. In this case a verbatim_short_name can be provided, and this value will be presented for reporting/searching purposes. This is a strong restriction that is intended to encourage users to think before they mint a Namespace.

In TaxonWorks Namespaces _do not_ imply ownership of the things they are linked to. If an identifier has a Namespace that includes a reference, in some way, to some Repository, it does not mean that that Repository ‘owns’ the identified thing.

In natural history collection management many catalog numbers contain an institutional coden as part of their catalog number (as physically written). In TaxonWorks we treat that coden as the basis for a Namespace. Note that we also may use the CODEN in a second way, to identify the Repository. While the string is duplicate the meaning is not. One use let’s us quickly reference a Repository, the second use let’s us quickly narrow searches to a specific Identifier linked to our object.

Returns:

  • (String) —

    The institution (loosely, could be a person) responsible for minting this Namespace. Roughly, where to look for more information. This is NOT 1:1 with rs.tdwg.org/dwc/terms/ownerInstitutionCode, which implies ownership. It is narrower in that it means the institution or individual “owns”, or minted this Namespace, that’s all.

  • (String) —

    The full, descriptive name of the namespace. For example ‘Illinois Natural History Collection Insect Collection Identifiers’.

  • (String) —

    A short, realized version of the name, as seen in the physical label if there is a physical form. For example “INHIC”. This may be embedded in rs.tdwg.org/dwc/terms/institutionCode. We presently do not differentiate a rs.tdwg.org/dwc/terms/collectionCode in identifiers, that data may(?) fall into Repositories.

  • (String) —

    TW enforces uniqueness of short names. When a short name exists for historical reasons but it has already been included in TW then a new short name must be minted, and a verbatim_short_name used to indicate the physically/and or historically recorded value.

  • (String, nil) —

    Defines the character(s) to be placed between the namespace short name and the identifier

  • (Boolean) —

    Defaults to false. If true then the namespace short name is not part of the “physical” identifier. Required to handle identifiers incoming

In natural history collection management many catalog numbers contain an institutional coden as part of their catalog number (as physically written). In TaxonWorks we treat that coden as the basis for a Namespace. Note that we also may use the CODEN in a second way, to identify the Repository. While the string is duplicate the meaning is not. One use let’s us quickly reference a Repository, the second use let’s us quickly narrow searches to a specific Identifier linked to our object.

from DwC in some contexts.

Returns:

  • (String) —

    The institution (loosely, could be a person) responsible for minting this Namespace. Roughly, where to look for more information. This is NOT 1:1 with rs.tdwg.org/dwc/terms/ownerInstitutionCode, which implies ownership. It is narrower in that it means the institution or individual “owns”, or minted this Namespace, that’s all.

  • (String) —

    The full, descriptive name of the namespace. For example ‘Illinois Natural History Collection Insect Collection Identifiers’.

  • (String) —

    A short, realized version of the name, as seen in the physical label if there is a physical form. For example “INHIC”. This may be embedded in rs.tdwg.org/dwc/terms/institutionCode. We presently do not differentiate a rs.tdwg.org/dwc/terms/collectionCode in identifiers, that data may(?) fall into Repositories.

  • (String) —

    TW enforces uniqueness of short names. When a short name exists for historical reasons but it has already been included in TW then a new short name must be minted, and a verbatim_short_name used to indicate the physically/and or historically recorded value.

  • (String, nil) —

    Defines the character(s) to be placed between the namespace short name and the identifier

  • (Boolean) —

    Defaults to false. If true then the namespace short name is not part of the “physical” identifier. Required to handle identifiers incoming

#verbatim_short_name ⇒ String, ...

A Namespace is used to define a set of local Identifiers. All identifiers within a Namespace must be unique. Namespaces are shared across projects. In TaxonWorks Identifiers + Namespaces are used for differentiating/disambiguating one datum from another. This applies to all local identifiers, not just what most might be familiar with in the DwC catalogNumber field.

Namespaces are used to to meet practical needs that also have FAIR consequences:

  • They attempt to provide a degree of provenance as to how the Identifier came to be

  • To differentiate, in practical terms, one identifier from another within the system that merges data

  • To act as a labels (short mneomincs) that allows the data curator to disambiguate what might be otherwise two identical strings

Namespaces are minted in TW on a first come first serve basis. Their short and long names must be unique. When conflicts arise new values must be minted for record keeping purposes. In this case a verbatim_short_name can be provided, and this value will be presented for reporting/searching purposes. This is a strong restriction that is intended to encourage users to think before they mint a Namespace.

In TaxonWorks Namespaces _do not_ imply ownership of the things they are linked to. If an identifier has a Namespace that includes a reference, in some way, to some Repository, it does not mean that that Repository ‘owns’ the identified thing.

In natural history collection management many catalog numbers contain an institutional coden as part of their catalog number (as physically written). In TaxonWorks we treat that coden as the basis for a Namespace. Note that we also may use the CODEN in a second way, to identify the Repository. While the string is duplicate the meaning is not. One use let’s us quickly reference a Repository, the second use let’s us quickly narrow searches to a specific Identifier linked to our object.
