Labels and definitions
Preferred label is the favoured label for the concept. It may have an optional language tag which, in the editor, you select from the drop down list.
Alternative labels are used for synonyms or spelling variants.
A hidden label is a label which you would like to be accessible to applications performing text-based indexing and search operations, but would not like that label to be visible otherwise. Hidden labels can, for instance, be used to include commonly misspelled variants.
Some classification schemes use notations as the primary means of access to the concepts they contain. Notations are symbols which are not normally recognisable as words/phrases in any natural language and are typically composed of digits, punctuation signs and other characters. For example, the Dewey decimal library classification system:
000 Computer science, knowledge & systems
005 Computer programming, programs & data
005.75 Specific types of data files and databases
005.756 Relational databases
The skos;notation property is used to record the details of the notation scheme.
skos:definition supplies a complete explanation of the intended meaning of a concept.
In the CEH vocabulary editor, definitions are stored as html and can therefore include rich text features such as styles (bold/italic/underlined), colours, images and hyperlinks.
It is unwise to delete publicly available concepts as they may be in use by users/systems. Rather than deleting a concept, it should be deprecated to indicate to potential users that the concept should no longer to be used.
To deprecate a concept, simply set the deprecated field to true.
Relationships in the SAME scheme
The broader relationship should be read as "has the broader concept", so, the example above means "mammal has the broader concept animal".
It is perfectly acceptable for a concept to have several broader concepts. So, for example, Iron could have both Metal and Chemical element broader concepts
The related relationship is symmetric. That is, if X is related to Y, then Y is related to X.
Relationships in a DIFFERENT scheme
Broad match/narrow match
skos:broadMatch and skos:narrowMatch closely mirror the skos:broader and skos:narrower associations detailed above. However, they are used to associate concepts in different concept schemes. For example:
Close match & exact match
Notes are used to provide extra information relating to concepts. There is no restriction on the nature of this information, e.g., it could be plain text, hypertext, or an image. You can include multiple notes in multiple languages.
The "Note" field can be used for general documentation purposes but there are several specialised note types for more specific types of information:
Documents fine-grained changes to a concept for the purposes of administration and maintenance. For example
Used to provide information to aid administration of the vocabulary, such as reminders of work still to be done or warnings that future changes might be made. For example
Used to describe changes to the meaning or the form of a concept. For example
Provides some information about the intended meaning of a concept, especially as an indication of how the use of the concept is limited in practice. For example
Supplies an example of the use of a concept. For example
