HAL is a multi-disciplinary open access
archive for the deposit and dissemination of sci-
entific research documents, whether they are pub-
lished or not. The documents may come from
teaching and research institutions in France or
abroad, or from public or private research centers.

L'archive ouverte pluridisciplinaire HAL, est
destinée au dépôt et à la diffusion de documents
scientifiques de niveau recherche, publiés ou non,
émanant des établissements d'enseignement et de
recherche français ou étrangers, des laboratoires
publics ou privés.

### Service and data catalog : routing data requests

RESIF-SI services and data catalog are published through the routing webservice.

The data provider defines priority data centers for the distribution of network data

The routing information is used by worldwide portals, federators and ObsPy in order to route the requests to the best datacenter.

#### Routing exemple with ObsPy

```python
>>> from obspy-clients.fdsn import RoutingClient
>>> client = RoutingClient("eida-routing")
>>> inv = client.get_stations(
...     channel="LHZ", starttime=UTCDateTime(2017, 1, 1),
...     endtime=UTCDateTime(2017, 1, 1, 0, 5), latitude=10,
...     level="channel", longitude=10, maxradius=25)
>>> print inv
```

## Data management workflows

Regional nodes **collect** the data, **validate** and **qualify** it. They create all **relevant metadata** and store the results at RESIF-DC

They **build the realtime data streams** that are concentrated and distributed at RESIF-DC

RESIF-DC stores, distributes and computes side products from the validated data. The metadata is made available for EPOS federator and other federated services.

All datasets are integrated in the ORFEUS-EIDA data distribution system, and in EPOS.

**Large-N** experiments yield high data volumes and scientific use cases are distinct from other networks. We built a separate workflow to manage these specificities

## Datacenter infrastructure

## Distribution statistics

<figure><img src="image_6.png" /></figure>

2 300 000 datasetect requests/month

5.7 TB distributed/month

70 TB of validated seismic data

70 Networks

## Future works

**Core Trust Seal Certification** RESIF-DC is taking part in the CEDRE ANR AGENCY NATIONALE DE LA RECHERCHE project aiming at certifying datacenters hosting earth

science data in France.

**Usage statistics webservice** RESIF-DC is developing a webservice to publish relevant statistics for the PIs

**YASMINE** Yet Another Stationxml Metadata Editor is an ongoing joint development IRIS/RESIF to provide a new tool for StationXML edition, featuring batch processing. This tool will be extensively used by regional nodes

**SICACO** a tool that automatically fills a seismic data archive, corrects overlaps and requests data to fill the gaps. Data are regularly fetched from a pool of different sources (seismic station, local archive...)

**Large-N data management**: We build a specific workflow to manage Large N experiences, store and distribute them as PH5 archives, using the PH5 suite. Work in progress to distribute the data selectively.
