We still don't have installation guide but pretty soon me and Loukik will prepare this. Roman Jason Zurawski wrote:

Hello all,
Some good news! We are all glad to let you know that phase 0 of the prototype is now complete! Although a bit overdue, we have managed to achieve what we planned to achieve and in the process, we have gained a significant amount of experience in doing similar work.
---Here is an overview of what was planned--- * Come up with a basic design of service components to ensure design pattern is followed in other services' design so and unnecessary work can be ruled out. * Provide the capability to retrieve measurement data from RRD (Round Robin Database) files * * Provide an optimised way of data retrieval. This is to reduce system overheads when data is asked repeatedly. * * A Web Service interface should be used for this purpose * * Any defined web service standards should be used * Use NM-WG version 2 schemas for communications * Come up with a new format of configuration files which store information about available rrd files and any related meta-data
---Here is what we achieved--- * Generic service design: We have designed interfaces for different components and we strongly think that they can be used for all types of services. * The capability to retrieve measurement data from RRD has been tested and declared to be working(+). Document/literal style of web services which seems to be the best suited in this case has been used. Optimised data retrieval methods have been put in place. * NM-WG version 2 schemas have been used for communications. Schemas and example-instances are available * New format of config file follows NM-WG version 2 schemas designed for storage. Usage of such config files have been tested and declared to be working * GEANT2 will be providing data for some interfaces on all its routers and for different classes of service. The existing test pilot service will soon start providing real time data.
---Highlights of some things that we have worked on which we see as important for this prototype--- * Generic Design of components of services * First use of NM-WG version 2 schemas * Well defined package structure for the project * Sophisticated logging mechanisms - usage of log4j * Error and exception handling definitions * Well managed service properties * Structured configuration file * SAX based reading of xml * In-line documentation using Javadoc * Easy to use build scripts and more...
Next steps include some documentation about what we have done and what we have learnt. Efforts are already underway here: http://monstera.man.poznan.pl/wiki/index.php/Coding_Standards.
We are positive that the delays that we experienced can be seen as initial delays (difficulties at lift off) and shouldn't be the same for later stages.
Best regards, Loukik.
