Frequently Asked Questions

Why is data restricted for XX network?
This is the decision of the PI/network operator for XX. Sometime an entire seismic network is restricted; other times only a few stations or channels may be restricted. Wherever possible, GEOFON attempts to provide open access to data, with at most a short embargo period. This is in line with GFZ’s guidelines (Grundsätze zum Umgang mit Forschungsdaten [PDF], March 2016).
I had access before. Why don’t I have access now?
Perhaps your token expired. See the next question.
I have been given access to another data set. Do I need a new token?
No. Your token identifies you (authentication). Together with data providers we separately configure which network(s) you have access to.
What do I do when my token expires?
Get a new one. You can do this by e-mail; see above.
Why don’t I have access?
We don’t know. You should contact the PI to request permission to access the data. If that fails, contact us, and we will try to contact the PI. If you and the PI both think you have permission, but it doesn’t work, we may not have configured our server with the necessary details. Please contact us.
Where is my token?

It was mailed to the e-mail address you provided, so it may be in your inbox. You can save it where you like. We suggest calling it token.asc.

TODO: What happens with fdsnws_fetch and no token? Silently supplies no data?

What is inside my token?

Your e-mail address, used to identify you to our server, and an expiration date. Use gpg with the –decrypt option to examine the signature:

$ gpg --decrypt token.asc
{"mail": "andres@gfz-potsdam.de", "valid_until": "2016-05-06T18:30:25Z"}
gpg: Signature made Wed 06 Apr 2016 06:30:25 PM UTC using RSA key ID CB981400
gpg: Good signature from "EIDA GFZ <eida@gfz-potsdam.de>"

In future, we may use additional attributes for authorising access, such as affiliation. For example, we could authorise anybody with affiliation researcher@alparray.ethz.ch to access certain data.

Is there a record of my access to the data?
Yes. We record the streams (channels, time windows) requested by users. This is shared with PIs/network operators, so that they have visibility into how data for their networks is being used.
What is eduGAIN?
eduGAIN is an service with the main objective of allowing users to authenticate at their home institutions and let them use services all around the world. Technically it is based on SAML [Security Assertion Markup Language]. About 2000 institutions currently have an Identity Provider (IdP) which is part of eduGAIN. Mostly, these are universities and research institutions. There are strict rules for an institution to be accepted as part of eduGAIN and these rules assure the quality of the credentials issued. These Identity Providers allow their users to log in locally and send their public attributes to any service which is accepted as part of eduGAIN.
Is my institute a member of eduGAIN?
Probably, yes. Here is a list of participating countries.
