The MANGO model proposes a flexible way to expose data related to astronomical source objects in an interoperable way.
- It takes into account the huge diversity of source data in terms of feature description, format and usage.
- The MANGO model attaches an identifier on an astronomical source and associates to it all data related : observed physical quantities called parameters in this context, and other information like spectra, time series, preview image, for instance,for that source.
- Parameters usually appear in the columns of a source catalogue. Additionnal dataproducts are bound to the source to contribute to the science analysis and enhance data understanding.
- Parameters are modeled by the IVOA MCT DM reusing both native and extended classes. Parameters' roles are given by UCDs and semantic tags.
- Associated data can be simple URLs, VO service endpoints or VO data model instances. Their roles are also qualified by semantic tags.
The process of creating the document is a bit complex due to the following facts:
- The model is maintained with Modelio which does not support any version control.
- It is designed in a way to make sure that the diagrams keep in sync with the UML.
- As the text Modelio edition is quite painful, it has been decided to store the description
of all model elements in individual files (
vodml/desc). - The VODML (without description) is generated by an XSLT
- The transformation of the VODML into Latex is done by another XSLT
- The items of the generated Latex are ordered following the VODML elements order, this must be corrected to have a consistent table of content
