| Abstract: |
The VLKB (Via Lactea Knowledge Base) consists of a set of heterogeneous collection of source catalogs (compact and diffuse), images and radio observational data cubes, including interface services for discovery and access. These latter ones allow positional search combined to spectral axes filtering and other constraints, and direct cut or mosaicking of the original datasets. The VLKB was initially built within the VIALACTEA EU-FP7 funded program and is now used and maintained within other EU funded programs (NEANIAS, ECOGAL), national projects and infrastructures (INAF CIRASA PRIN and INAF IA2 data center). A TAP service provides access to the catalog part of the database while dataset collections are available through a discovery interface to identify the wanted cubes and images, and two services: one devoted to cutting the images or cubes based on positional or spectral axis bounds and another merging adjacent datasets whether the positional boundaries overlap multiple of them. This contribution focuses on the datasets access, cutout and merge services, originally presented through proprietary interfaces and now under refurbishment using standardised interfaces leveraging IVOA protocols and other technology standards. |
