OPENCoastS user manual

OPENCoastS is an online service (https://opencoasts.ncg.ingrid.pt/) that assembles on-demand circulation forecast systems for selected coastal areas and keeps them running operationally for a period defined by the user. This service generates daily forecasts of water levels and vertically averaged velocities over the region of interest for 48 hours, based on numerical simulations of all relevant physical processes. Presently, all forecasts are made with the model SCHISM (http://ccrm.vims.edu/schismweb/) and are supported by the computational resources from INCD - Infraestrutura Nacional de Computação Distríbuida (https://www.incd.pt), a node of the EGI - European Grid Infrastructure (https://www.egi.eu). Access to the service is granted through a registration procedure, and is obtained after acceptance of the registration by the OPENCoastS user support. OPENCoastS is jointly developed and maintained by LNEC - Laboratório Nacional de Engenharia Civil (LNEC - http://www.lnec.pt), LIP - Laboratório de Instrumentação e Física Experimental de Partículas (LIP - https://www.lip.pt), CNRS-LIENS - Centre National De La Recherche Scientifique - LIttoral ENvironnement et Sociétés (CNRS-LIENS - https://lienss.univ-larochelle.fr) and Universidad de Cantabria (UC - https://web.unican.es).

Federated AAI for EIDA Services

EIDA is the European Integrated Data Archive infrastructure within ORFEUS to provide access to seismic waveform data and related metadata in European archives. EIDA has been stablised in 2013. EPOS-ORFEUS Competence Center works on new federated seismological services for EIDA. The presentation slides introduced the new Authentication and Authorization for EIDA developed by the CC. The two presentations were given in EGU 2019 conference, April 10th 2019, Vienna, and in EPOS Seismology Meeting, May 7th 2019, Potsdam, respectively.

A user documentaion is also avaialbe at: https://geofon.gfz-potsdam.de/eas/EIDAAuthenticationService.pdf

Transparent data movement from EGI to EUDAT

The main goal of the EOSC-hub project is to synergize the services and infrastructures from major European providers including EGI and EUDAT, enabling researchers to freedom of choice of the services, data and infrastructure necessary for their work. Users from many communities have reported interest in being able to use resources provisioned by these 2 infrastructures simultaneously in a transparent fashion, i.e.:

using single sign on mechanisms between infrastructures
being able to transparently transfer data between infrastructures

EOSC-hub WP6 has been endeavoring to enable transparent data access between the infrastructures. The main data management components in EGI and EUDAT are respectively, EGI-DataHub based on Onedata platform and B2SAFE/B2STAGE based on iRODS. Currently no transparent mechanisms allowing users to move data between these infrastructures exists, the only options are manual transfers using such tools as GridFTP.

These two demo videos present the managment of data transfer across EGI, EUDAT, INDIGO data and compute services.

The first demo video shows the how data can be transparently moved from EGI to EUDAT. It divided into 4 sections:

Registration of B2STAGE storage in EGI-DataHub
Creation of dsata space in EGI-DataHub supported by the B2STAGE storage
Upload of some data to the data space
Data access from GUI and command line

The second demo video presents import of existing data from EUDAT to EGI. The demo is divided into the following 4 sections:

Registration of B2STAGE storage in EGI-DataHub
Creation of data space in EGI-DataHub supported by the B2STAGE storage from which existing data is imported to EGI-DataHub
Access of data from B2STAGE using EGI-DataHub user interface
Automatic discovery of new data added on the B2STAGE storage

Training on the EOSC-hub AAI--The service provider perspective

This training materilas is provided for the AAI training during EOSC-hub week 2019, 12 Apr 2019, Prague. This material provides an overview of the various integration workflows in support of resource providers’ needs for federated access through the EOSC-hub AAI. These workflows build on standards and open technologies, including SAML 2.0, OpenID Connect, and OAuth 2.0, in order to support the integration of web-based services. The training also covers more advanced workflows for addressing non-web-based access use cases (e.g. command line and API). In this context techniques for obtaining credentials on behalf of the end-user using OAuth tokens and X509 proxy certificates through online authorities will be presented.
