New data catalogue now availablePosted on September 30, 2014 (Last modified on October 19, 2023) • 5 min read • 913 words
CEDA’s new data catalogue service was made public earlier today, delivering an improved and more sustainable interface for users to search, discover and access the content held in the BADC, NEODC and UKSSDC data archives.
Our new catalogue has been built on international standards after a number of years of development, and with care to preserve, develop and enhance the content and functionality that users will be accustomed to from our previous catalogue.
The new catalogue has been designed to help users:
Although the catalogue has been designed to be more intuitive to user than the previous catalogue, CEDA have put together a short introduction on using the new catalogue. This describes the main features of the catalogue and new users are encouraged to read this before starting to explore the catalogue.
The new catalogue is designed around the following key linked features: Datasets, Dataset Collections, Projects, Instruments, Platforms and Computations.
Dataset records provide detailed information about specific datasets held in the CEDA archives - for example, data from a particular instrument on a field campaign; while Dataset Collections bring together series of these datasets, linked by some common theme - e.g. a field campaign, a particular instrument or facility.
Project records provide background information about why the dataset was produced and may also have links to supporting services for ongoing projects that CEDA is actively supporting - such as group workspaces or information about depositing data for the project participants.
Instruments, Platforms and Computation records give relevant information about how and sometimes wheredata were produced. For example, these can tell you about an institution’s chemistry information mounted on a research aircraft, or a particular NWP model run on a supercomputer.
Users can then navigate from one record type to another to find either related data and/or related background information.

If you require further assistance or would like to make any comment about the new interface, please contact the CEDA helpdesk and we will be happy to assist where possible.
Most of the new catalogue’s main features are synonymous with our previous catalogue, but have been made ISO standards compliant by adjusting and standardising the content of the different record types in the catalogue. In some cases there wasn’t a direct mapping and so the information has been split where needed.
The table below shows how the items in the old catalogue have been mapped to the new service:
|Old catalogue||New catalogue|
|Data Entity||maps to||Dataset Collection|
|Data Production Tool||for observational tools maps to||Instrument|
|for models maps to||Computation|
|Observation Stations||for observational stations maps to||Platforms|
|for computer hardware maps to||Computation|
With the switch to the new catalogue service CEDA are taking careful steps to maintain the traceability of our data and how people may have previously cited data in our archive in publications. To do this CEDA has:
At present the new catalogue is largely a like for like replacement of the present catalogue and you can still explore the old catalogue here.
The old catalogue will be switched off around the start of November this year to allow people to transition from the old catalogue to the new service. However, we are planning on continuing to improve the new service by:
As mentioned above, the new service has been designed to comply with international standards which allows more greater portability of the catalogue information to external services - such as the NERC Data Catalogue Service. The standard CEDA has followed is a GEMINI 2 and INSPIRE compliant standard with an environmental focus, built around version 3.4 of the MOLES (Metadata Objects Linking Environmental Sciences) model, developed by CEDA.
