Configuring your repository particularly means that you set up so-called properties that you and your maintainers will use to describe concepts and terms. Typical properties we often see in repositories are for instance Definition, Usage Status, Gender or also Graphic. The set of properties acts like a template, like a blueprint, to guide the maintainers what additional information should be stored together with concepts and terms.

Note: What Coreon calls a property you may find in other solutions under the terms data category, descriptive field or generally as meta data.

Coreon has an open data model. That means that you define yourself what properties you need. In a closed data model, for instance SKOS, you only have a limited, predefined set of properties available. In Coreon however, you have maximum flexibility what properties you need to describe your world. Of course, the set of properties is usually different from repository to repository.

What is a data type? A data type is a technical restriction that specifies what values a property, i.e. a given input field, can accept. For instance, a property with a numerical data type only accepts numbers, whereas a text data type accepts any textual character.

Why these data types? Why not always just text, where you can type in any information? A property has a key (i.e. its name) and a data type. Together they achieve one main thing: Consistency!

  • Key: Via the property key you make sure that in your repository you would always and only for instance see Comment and not here and there also Note. Simply because you want that all notes, thoughts, comments show up in the property named Comment.
  • Data Type: Via the data type you restrict the potential values that can be typed in into a given property. This guarantees a) data integrity but b) also increases usability for the maintainer.

What data types are available in Coreon?

  • Text: A single line of text.
    Sample: Origin – for instance to add a quick reference, note, or a link to where a given information comes from
  • Multiline Text: Several lines or paragraphs of texts, including bulleted or numbered lists.
    Sample: Definition or Comment
  • Picklist: A list of values, where only one option can be selected
    Sample: Usage Status with the value options PreferredAllowedForbidden – for instance to rate a term.
  • Multiselect Picklist: A list of values, where one or more options can be selected
    Sample: Confidentiality with the value options Team onlyCompany InternalPartner NetworkEveryone, – for instance to specify whether a concept is for which audiences ok to be published.
  • Number: Numerical values
  • Flag: Boolean-like yes / no resp. true / false
  • Date: ISO 8601 compliant date and time string
    Sample: Approved On , to track the milestone when a concept has been finally approved
  • Asset: Uploadable multimedia files (image, video, sound as well as pdfs).
    Note: Images are nicely rendered directly in the browser

How does this improve usability when editing concepts and terms? The Coreon UI reacts on the data types. Instead of just and always showing an input field, for instance, for a picklist data type only the value options are shown and selectable. Thus you achieve consistency and it makes you way faster when editing content.

Finally, where can you define these properties, the model of your concepts? This is part of the repository configuration. Find it in the dashboard in the Model tab.
