Overview¶

This document contains information about the deployment, status of OpenAIRE2020 services and content, and the history of major modifications of the system hosted at ICM, Poland.

The official maintenance of the OpenAIRE2020 services began on January 1st, 2015 when the project started.

Deployment¶

Because OpenAIRE2020 services are a continuation and incremental extension of the services already present that resulted from OpenAIRE+ project, so they are still hosted on that same machines. More details are available at OpenAIRE+ WP5 Maintenance Report.

@Paweł: are there any new services in maintenance since OpenAIRE+ project worth mentioning here?

Documentation¶

DNet deployment is performed following the documentation described at: http://ivy.driver.research-infrastructures.eu/ci/dnet-openaire-doc/

@Claudio: is it up to date?

The Orphan repository is deployed according to the process described at http://invenio-software.org/wiki/Project/OpenAIREplus/ReleaseProcess.

@Lars: link does not work anymore, can you provide the proper one?

Information Inference Service versioning and deployment is described on IIS versioning and deployment wiki page. More detailed description of IIS deployment is available on IIS deployment step by step wiki page.
