OpenEM Operator Manual

Introduction

This section documents the installation and maintenance of facility-related OpenEM components.

The instructions are aimed at administrators of OpenEM components managed by the facilities. For questions and problems regarding infrastructure outside the facility, use the appropriate support channels.

Basic infrastructure

OpenEM provides infrastructure for managing, cataloguing and storing research data. The catalogue is provided through SciCat. The Ingestor component transfers large EM datasets and runs the metadata extractor. The extracted metadata supports structured filing according to the FAIR principles.

Responsibilities

OpenEM infrastructure can be divided into three responsibility groups.

The storage infrastructure and Ingestor component are hosted by the university or research institution. The facility must ensure that the transfer server and raw-data storage system are operational. The Ingestor, which runs on the transfer server, is the core component for data transfer.

SciCat and the target server for file transfer are the responsibility of PSI and ETHZ. This includes the Ingestor frontend integrated into the SciCat environment.

Long-term storage is managed by CSCS or ETHZ. Data is archived for the long term and can be requested by users when required. The request is made directly in SciCat, which then makes the data available for download on the cache server.

Development

PSI and the open-source community maintain and further develop the components. The open-source code allows users to implement individual development requests.
