Email subscription utility for updates in Dyntaxa.

Abstract: Dyntaxa is a database system where one can find information about the Swedish animals and plants such as name(s), taxonomic hierarchy, and Swedish occurrence. One of the Dyntaxa’s requirements is that anyone should be able to subscribe and receive information about taxon’s updates by email. This is the task given by Artdatabanken at SLU that this thesis solves. The report describes the developed email subscription utility for the Dyntaxa system. In the developed utility one can subscribe to any of the animals, organisms or plants existing in the database, and receive an email when data is updated. Furthermore, a study of three different message queue libraries was carried out in order to see the positive and negative features, and to choose the most well suited queue library for Dyntaxa. The email subscription utility is now a working prototype that needs some more testing and minor changes to be put into production.
