FAQ

Data and datasets

What kind of data can I find in ECDS?
ECDS contains different kinds of data from all aspects of climate and environment. The data portal includes metadata for datasets, and links or references to the data sources. The ECDS metadata profile is based on the international standard ISO 19115.
Open data can lead to new ideas of how to use and combine data from different sources and provide opportunities to find new collaborators in other disciplines.

Where do I find the data publication plan?
A new Data Management and Sharing Plan template will be available soon. In the meantime, please consulte relevant sources for advice, such as

SND's Datahanteringsplan page (in Swedish)

Digital Curation Centre's (DCC's) Data Management Plan Checklist

Data owner responsibilities?
Data submitted to ECDS is a copy of the data. The full ownership rights, including intellectual property and archives responsibility, remains with the principal researcher. Submitting data to ECDS does not legally make the data into a public document, and is considered as technical restructuring and storage on behalf of the principal researcher.

Which data formats do the ECDS data portal support?
You can use any format as long as you can describe it and explain what is needed for reading the data.
A lot of data formats are in use by different communities. Text (csv) and Microsoft Excel formats are used universally. Popular formats in the meteorological, oceanography and climate communities include Grib, NetCDF and Hdf. Open-access spatial data is typically stored as Shapefile or GeoTIFF.
Most important is that you describe your data as detailed as possible, to ease for other users to reuse the data resource.

Which data format standard shall I choose for my data?
A lot of data formats are in use by different communities. In the meteorological, oceanography and climate communities and, in particular the modelling communities, popular formats include:
Grib
NetCDF, Home
NetCDF Documentation
NetCDF Integrated Data Viewer
Hdf

Where do I register my metadata and datasets?
The metadata and the dataset are both registered and managed at once, in the same portal. First you add your metadata, and then you upload your dataset. You can change visibility from Private to Public when your registration is finished. Then the information will be visible.

How to upload my datasets?
When you have filled in metadata information, you can proceed to step two, where you can upload your datasets. You can upload several files. If you have a lot of files, we suggest that you compress your files in some kind of zip archive before you upload them. This makes it easier for another user to download all data.

How do I edit my metadata and datasets?
Login and go to your dataset. To edit the information, press the Manage button to the right of the tabs above the headline.

Metadata

Why metadata?
Metadata are used to describe a dataset and to provide information about What-Where-When-Who-How.

How to choose standard for my metadata?
A general advice is to build on standards and formats already in use by the respective community as far as possible. This will not only prevent you from reinventing the wheel (which saves time and money), but also to avoid a multitude of different individual solutions to often very similar problems (which in turn might make it difficult for others to use and benefit from your data).
Specific communities may have different requirements on how datasets should be described. In the climate community, e.g., huge efforts have been committed to the creation of metadata conventions, in particular with regard to requirements from coordinated global and regional climate model experiments for the IPCC.

Store data

Does the ownership of data change, if I store them through ECDS?
ECDS will not take over ownership of datasets, but acts as a host for the data. ECDS is not responsible for updating data or metadata, version management of format conversions, as this is the responsibility of the data owner. The owner is also responsible for archiving the data.

What is the difference between storage and archiving?
When you store your data in an open data portal you give other users the possibility to access and download your data in an open and transparent way. But, this storage does not replace your responsibility to archive data. This means that the data owner should always have their own archive solution in parallel to sharing data through the ECDS portal.

How can I administrate my data, originally stored at Swestore through ECDS?
Please contact the ECDS team by sending an e-mail to ecds@snd.gu.se.

Share data

How do I share my data?
First you have to register to the portal. Go to the registration page. Then you have to join an organisation, go to the list of organisations, select an organisation and tap the Join button. If you can't find an appropriate organisation, you can add a new organisation.
Now you are ready to go to the Publish page where you can start to fill in your metadata, and then add your data.

I have published my data, but still I can't find them among the datasets!
Check the Visibility option in the metadata form (scroll down to the bottom of the page). If you change visibility from Private to Public your data will be visible.

Can you harvest data from my portal into the ECDS portal?
Please contact the ECDS team for further assistance.

Tools and visualisation

How to visualise my data?
Many users in the environment and climate domain use GIS-applications for the visualization or analysis of data. An extensive list of popular raster and vector GIS-formats can be found at:
GIS-formats
OGC-standards for gwospatial and location based services

Where can I find tools for working with GIS-data?
For GIS-formats there is a variety of commercial and non-commercial tools available. The latter includes both viewers, simpler tools for analysis as well as fully fledged GIS-applications, e.g.:
GRASS-GIS
OpenEV
QGIS
Tools for the conversion of GIS-formats (raster and vector) can be found at, e.g.:
GDAL

Where do I find tools for working with data in Grib or NetCDF?
Useful tools for working with Grib and/or netcdf include, e.g.:
CDO Climate Data Operators
NCO Operators
Grads

Where can I find other services for management and distribution of data?
Visit e.g. Thredds and Dataverse for more information.
Thredds
Dataverse Network

Organisations and groups

Organisations, what is organisations and how should I use them?
The ECDS portal is built on the CKAN open source software for open access to data. The software organises data out of organisation, and therefore you have to connect each dataset to an organisation.
There are cases where there are several organisations that are responsible for a dataset. To associate the dataset to more than one organsiation, we suggest that you create a group and add the dataset to the group as well.

Groups, what is groups and how should I use them?
A group is a collection of datasets in the ECDS portal. You can use groups to create and manage collections of datasets. This could be to catalogue datasets for a particular project or team, or on a particular theme, or as a very simple way to help people find and search your own published datasets.

How do I create a group?
You can make your own group of data by going to the Groups page, and add a new group. Then you can add datasets to your group by selecting the dataset, select the Groups tab and add it to a group in the drop down menue. To remove a dataset from a group, go to the dataset, select the Groups tab and tap the Remove button visible with the cursor above the group name


Metadata profile

What is a metadata profile?
Metadata is a key concept – it is the information about a dataset. The information answers the questions: What? Where? When? How? Who? The information is structured according to a metadata profile that contains elements in a certain order and with a defined content.

What about the ECDS metadata profile?
A user who wants to make data visible in the ECDS data portal will need to fill in the information about the dataset according to the relevant metadata profile, in order to make it searchable by other users.
You can find detailed information on the ECDS metadata profile at the metadata profile page.


ECDS project

Where do I find information about the ECDS project?
You can find more information about the project at the project info page at ecds.se/about
