SourceCollection Hierarchy

This package contains the SourceCollection classes which extend the Astro-WISE principles of data pulling, data lineage and persistent data to catalog data.

A SourceCollection object represents a tabular structure where each row represents a source (identified by SLID/SID combination) and each column an attribute. The data represented by a SourceCollection is defined by an operation on other SourceCollections or other data objects. Every subclass of the SourceCollection represents a specific operator.

TODO MT M: [NOCAT] Improve on this documentation.

List of Classes with Persistent Attributes:

• SourceCollection persistent properties:

  • SCID
  • parent_collection, parent_collections
  • name
  • creation_date

  auxiliary persistent properties:

  • sourcelist_data, link to a SL
  • sourcelist_sources, link to a SL
  • attribute_columns
  • attribute_names
  • all_data_stored, Flag to indicate whether it has been determined that all data is stored

• ConcatenateAttributes

• ConcatenateSources

• SelectAttributes - selected_attributes

• SelectSources - selected_sources, another SC that contains the selection of sources

• FilterSources - query, string representation of selection criterion (WHERE clause of SQL)

• RenameAttributes - attributes_old - attributes_new

• RelabelSources - associatelist, link to the AssociateList that contains the association

• SourceListWrapper - sourcelist

• External

• Pass

• AttributeCalculator - definition, a link to the AttributeCalculatorDefinition object responsible for the calculation - process_parameters
