TagTick: a tool for annotation tagging over Solr indexes

"Annotation tagging" is an important curation action per- formed by authorized data curators willing to classify ac- cording to a common vocabulary an Information Space of potentially heterogeneous objects (e.g. not sharing common classification schemes). To carry out their activities, data curators need annotation tagging tools which allow them to bulk tag or untag large sets of objects in temporary work sessions, where they can experiment in real-time the object of their actions before making the changes visible to end-users. Real-time temporary bulk tagging is a non trivial feature to implement, which strictly depends on the back-end used to index the Information Space. This demo presents TagTick, a tool which offers to data curators a fully functional annotation tagging environment over full-text index Apache Solr, considered a "de facto standard" in the field.
