How Can We Help?
Classification schemesClassification schemes
Classifications are fixed values which users add to content instead of free text. This allows
institutions to control the input of certain data in Pure according to their policies, resulting in
increased data quality and making it faster for users to enter data.
Classifications are grouped together under classification schemes, which are curated lists
of values that appear in certain places throughout an institution’s Pure.
Overview
For example, when adding a country value to an External organisation record, the country value “Denmark” is a
classification, and the whole list of countries that can be added is the classification scheme.
Illustrated above is the the classification "Denmark" within the classification scheme "Countries (ISO3166-1)".
Another example is using values as keywords on a specific content type. When those keywords comes from a predefined list, this equals a classification scheme.
Finding classification schemes
All classification schemes are found in Master Data > Classification schemes.
The best way to search for a scheme is by name (description) of it, the URI or any (distinct) value from the scheme.<
Classification editor
When you create a new scheme, or open an existing, the classification editor has two main areas:
- Scheme
- This is where the scheme specific metadata fields exist.
- Classifications
- This is where the related values to the scheme exist.
Scheme
The table below describes in more detail these fields.
| Field | Description | More information |
|---|---|---|
| URI |
The URI always starts with this /dk/atira/pure/keywords/ followed by a given name relevant for what it contains:
|
Classification Schemes: URI Validation on Special Characters |
| Type | Has no practical consequences, this is just for categorisation of the classification schemes. | Type Field in Classification Schemes |
| Description | This is the name the scheme is found/listed/searchable by. Consider it the title of the scheme. |
Values
This is where you can add the individual values that the scheme holds.
Please be aware of the limit of possible values: Classification/Structured Keyword Volume Limits
Adding values manually
see Create Custom Classification Scheme for Use as Keywords for a detailed example of this. This approach works best if it is a limited amount of values.
Adding values by import
If you have a bigger set of values you should consider Import a Controlled Vocabulary/Taxonomy
Deleting a classification scheme
In case a custom classification scheme is not going to be used anymore, it can be deleted using the red X in the bottom of the editor.
Not all classification schemes can be deleted as Pure is dependent on some of these.
- If the classification scheme was created by any of the users: atira, root, sync_user, anonymous or webservice, it can not be deleted.
- If the classification scheme was created by other users, deletion will work
