In the last weeks we`ve been working on several back end and front end features.

Back End: Optimization of the users` waveform requests management

We have adopted ActiveMQ as our requests message broker. We foresee this as one the core tools to centralize and schedule all the incoming waveform requests at the ODC, that will be routed transparently to the nodes of the ArcLink network.

We aim to extend this system to serve not only the portal but also other client tools, eg Breqfast.

Front End: Dataset Rating

Through the NERIES portal and cyberinfrastructure, the users of the portal can search for eartquakes and waveform by aggreagating in a transparent way information coming from different and multi domain data providers, having access to a big amount of seismic stations (c.a. 600 at this early stage) available through the ArcLink network

The adoption of Web 2.0 technologies such as webservices, RDF, and feeds coupled with Ajax and interactive maps, gave us the possibility to search, combining and mashup the seismic information that are distributed over the internet

Each user can compose his own dataset , combining together earthquake parameters, station information, phases arrival times in a completely dynamic way, thus exempting the providers from "guessing", processing and then offering, pre-packed datasets.

The datasets are basically created on demand from the users themselves.

In order to improve our services we have implemented an easy to use rating system which will help us in tracking back how users search for data, giving them the possibility to provide a quality evaluation on the obtained dataset. A negative feedback will be notified to the organisation providing the data which compose the user`s dataset, whilst all the positive ones will be used to create a collection of user composed datasets and metadata that will be made available to the users either through the NERIES Data Portal or through RSS feeds.

Please, find below the screenshot of the requests detail page hosting the Rating functionality

All comments and ideas on how we could improve this service are more than welcome!!
