One of the aims of the European Integrated Data Archive (EIDA) is to provide transparent access and services to high quality, seismic data across different data archives in Europe. In the context of the design of the EIDA New Generation (EIDA-NG) software we envision a future in which many different data centers offer data products using compatible types of services, but pertaining to different seismic objects, such as waveforms, inventory, or event data. EIDA provides one example, in which data centers (the EIDA “nodes”) have long offered Arclink and Seedlink services, and now offer FDSN web services, for accessing their holdings. In keeping with the distributed nature of EIDA, these services could run at different nodes. Depending on the type of service, these may only provide information about a reduced subset of all the available waveforms.

To assist users to locate data, we have designed a Routing Service, which could run at EIDA nodes or elsewhere, including on a user's personal computer. This (meta)service is supposed to be queried by clients (or other services) in order to localize the address(es) where the desired information is provided.

The Routing Service must serve this information in order to help the development of smart clients and/or services of higher level, which can offer the user an integrated view of the whole EIDA, hiding the complexity of its internal structure. However, the Routing Service need not be aware of the extent of the content offered by each service, avoiding the need for a large synchronised database at any place.

The service is intended to be open and able to be queried by anyone without the need of credentials or authentication.

The installation instructions are included in the package, but need first to be generated. Follow the instructions in the next section to do it.

To get the documentation of the current version of the Routing Service you please follow these steps:

1. Go to the "doc" subdirectory located where the package was decompressed. Let's suppose it is "/var/www/eidaws/routing/1". :

$ cd /var/www/eidaws/routing/1/doc

2. Build the documentation. :

$ make latexpdf

3. Open the generated PDF file with an appropriate application (e.g. acroread, evince, etc). The file will be located under the .build/latex directory. :

$ acroread .build/latex/Routing-WS.pdf

Copy this file to the location most suitable to you for future use.
