Why this library?
In order to help Java developpers to quickly build a TAP service with as less code writing as possible. A service built using this framework will be conform to the IVOA definition of the protocol TAP.
- Configuration file: a TAP service can be created with just a simple key-value configuration file...nothing else.
- Metadata management: a TAP service let querying a database whose some tables and columns are accessible. All information (name, ucd, utype, type, description, ...) about them must be provided to the library. Easy ways (e.g. read file, database import) to give these information are provided by the library.
- Home page: a default home page with an HTML form is provided by this library for the root resource of the service. This home page can be changed.
- Authentication: thanks to a simple Java interface, the library let developers specify a way to identify a user. No default authentication method is provided.
- Log: all infos, warnings and errors are reported in a log. Log format is let free to the library users: it can be a file (free format), a database, a set of files, ...
- Backup: asynchronous jobs (query + result) of the resource /async are stored on the server. Thus they can be restored at service restart.
- Upload: VOTable(s) can be uploaded and crossmatched with the TAP service tables. This feature can disable by default.
