Overview

DEIMS-SDR (Dynamic Ecological Information Management System - Site and Dataset Registry; https://deims.org) is a web service that allows registering and discovering long-term ecosystem research sites around the globe, along with the data gathered at those sites and the people and networks associated with them. DEIMS-SDR describes a wide range of sites, providing a wealth of information, including each site’s location, ecosystems, facilities, parameters measured and research themes. It aims to be a globally comprehensive site catalogue of in-situ observation or experimentation facilities covering all (terrestrial) biomes and enabling that standardised information to be openly available to science, politics and the public in general.

Scientific Objectives

• Easy discovery of sites and their associated data
• Persistent, unique and resolvable identification of sites
• Allowing comparative analyses of registered sites and their networks

Description

Architecture

DEIMS-SDR currently consists of four main components fulfilling different needs and offering linked services:

...

 The relation and interfaces of all software components are illustrated in Fig. 4. The support of WMS and WFS allows for on the fly usage of site information in desktop GIS applications, such as QGIS, or online applications using JavaScript libraries, like OpenLayers orLeaflet. CSW and OAI-PMH ensure interoperability with other metadata catalogues, like other instances of pyCSW or GeoNetwork. This allows data on DEIMS-SDR to be harvested by external systems, e.g. the GEOSS Portal http://www.geoportal.org/) or DataONE (https://www.dataone.org/). Additionally, simple CSV exports can be generated covering basic information about research sites and datasets.

Advantages

• Issues neutral site identifiers, which allow cross-RI site identification
• Online production service with long-term funding
• Well established in the LTER community and successfully used in a number of project (ENVRIplus, EcoPotential, eLTER, ...)
