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.
