  In this paper we describe the way the Astro-WISE information system (or
simply Astro-WISE) supports the data from a wide range of in- struments and
combines multiple surveys and their catalogues. Astro-WISE allows ingesting of
data from any optical instrument, survey or catalogue, pro- cessing of this
data to create new catalogues and bringing in data from different surveys into
a single catalogue, keeping all dependencies back to the original data. Full
data lineage is kept on each step of compiling a new catalogue with an ability
to add a new data source recursively. With these features, Astro- WISE allows
not only combining and retrieving data from multiple surveys, but performing
scientific data reduction and data mining down to the rawest data in the data
processing chain within a single environment.
