Domain can be used as MetaNodes or MetaResources. For example,
a Domain viewed as a MetaNode can search for all emerging movements
and compare it with its capacity.
Structure is:
- base domain (like base category)
- sub domain (like category)
Allows to define ranges:
- price between X and Y
- portal_type in (a, b, c)
- price between X and Y and region in (a, b, c)
Reports:
- listbox allows to produce reports
- output to html, pdf or ooffice
- definition through the web (ie. which field in which column, which statistics)
- definition of selection (to list)
- ability for use to "save" favourite report (user reports)
- library of favourite reports (global reports)
- matrixbox allows to produce reports
- output to html, pdf or ooffice
- definition through the web (ie. which base_category or base_domain in which axis)
- definition of selection (to map to matrix)
- ability for use to "save" favourite report (user reports)
- library of favourite reports (global reports)
Domain and Domain Generators are now unified. Any domain may act
as a domain generator or as a simple predicate.
A Domain Generator uses a method (SQL, Python) to select objects
which are then wrapped as Virtual Domains. This can be used for
example to provide the list the 10 best selling shops to
a report tree.
