Metadata

Working with Link-Metadata.
Featurepacks:

Foldie metadata is inspired from the Resource Description Framework (RDF), but much simpler. A Metadata entry is represented by a subject-predicate-object-triple (Link, Attribute, Value), where Link is a Foldie Link URL, Attribute is a user-defined name such as “tag”, “quality”, “basedOn”, and Value is single- or multiline plain text that may contain other links.

A link property is an (Attribute, Value) pair, and a mention of a link is a metadata entry, in which the link occurs in the value field.

You can attach arbitrary properties to the current link in the file browser. You can see at the tag icon that a link has properties or is mentioned in metadata of other links.

You can create a new property and set text values for the attribute and value fields. Or you select an existing attribute and an existing values for that attribute.

This way you can tag your links, add info-notes, attach related links.

The file browser also shows you mentions.

The metadata browser

The metadata browser shows all entries, but you can filter them in different ways:

  • Use the search field to find triples that contain some text.
  • Tap on a link to find triples that contain the link. If you tap on a project folder, all links to subfolders match.
  • You can further filter by requesting that the link is part of the link field or part of the value field.
  • You can choose to show a subset of existing attributes.
  • You can filter the triples to show a specific attribute, value or attribute-value combination.

Interaction modes:

  • In open-link-mode (share icon) when you tap on a link, that link is opened.
  • In metadata-browse mode (right arrow), when you tap a link, you replace the link filter with the new link. This way you can walk the graph of links.
  • In edit mode (pencil icon) you can select and delete entries.
