Bulk update collections in an automatic fashion

[SvenLieber]

With SFM, collections can be created and configured via a user interface. This includes the addition of seeds to collections which should be harvested. However, since in BESOCIAL we would like to experiment with semi-automatic ways to extend social media collections, e.g. identifying new seeds by applying social network analysis on harvested data, we would like to have a way to configure collections in bulk mode.

A bulk mode would be needed such that we don't need to manually insert/update possibly large seed lists by users.

This use case includes updating a collection, adding seeds and ideally leaving a provenance trace expressing which automatic component added which seed and why. There are several ways to accomplish this, one straight-forward way would be a bulk-insert script which directly adds/updates information in the PostgreSQL database.
