Metadata

Any entity can be annotated with metadata, which can be used for searching. In Datagrok, there are three kinds of metadata: tags, parameters, and properties.

Tags​

A tag is a short string that can be associated with any entity. It is convenient for grouping things (potentially of different kings) together.

To search for tagged entities, enter '#tagname' in the search box.

Parameters​

Each entity can be associated with a list of key-value pairs.

To search for entities with the specified parameters, use the <paramName> <op> <value> syntax, for instance:

  • imported < 10/02/2019
  • rows > 200
  • author = @current

Properties​

Properties are somewhat similar to parameters, however they might contain nested properties; also, they are not directly editable. Some properties are common for all entities, others are specific to the entity type.

Common properties:

  • ID
  • name
  • author
  • createdOn
  • updatedOn
  • commentedBy
  • usedBy
  • starredBy

Search criteria can be combined using 'and' or 'or' operands:

  • #demo or #chem
