What is metadata?¶
Metadata is data describing the dataset itself. This is a set of fields describing the data, such as a title, a description, a list of keywords, a modification date, or whether the dataset is compliant to a specific geospatial norm. Adding metadata on a dataset is important to make sure it can be found, understood, and reused by users. In some cases, it can also be important for interoperability, to make sure other systems can understand the content of the dataset.
Different kinds of metadata¶
The OpenDataSoft platform considers three kinds of metadata:
- basic: this is the information users can see in the “Informations” tab of your dataset, and is generally intended to be readable by humans. This includes the title, the license attached to the data... If you want an information to be seen by users on the portal, it should probably be a basic metadata.
- interoperability: metadata usually described in specific standards (such as DCAT or INSPIRE), intended for automatic usage by other systems for interoperability purposes, or for regulatory compliance.
- extra: metadata intended for specific applications, and not expected to be used by users directly. For example, if you configure your default visualizations on the OpenDataSoft portal, this information is stored as an extra metadata. In most cases, you will never have to access or edit them by yourself.
When creating or editing a dataset from the back-office, you can fill the metadata from the “Information” tab.
You are presented with a form representing all the available metadata to fill for the dataset. The first part of the form represents all the basic metadata. The second part of the form represent the groups of interoperability metadata available on the portal.
The following metadata fields are available by default:
- Title: the title of the dataset
- Description: the full description of the dataset (HTML is accepted)
- Geographic area: the geographical coverage of the data
- Last modification: the last modification date of the dataset (manually set)
- Language: the language (as a two-letter language code) of the dataset’s data and metadata
- License: the license attached to the dataset; should always be filled for any public dataset
- Theme: one or more themes associated to the dataset (Environment...)
- Keywords: one or more keywords for the dataset, mostly used to make it easier to find in the catalog
- Publisher: the publisher of the dataset (the name of a person or of an organization)
- References: one or more links to indicate the references or sources of the dataset
Customizing available metadata¶
It is possible to add custom metadata, or groups of metadata on an OpenDataSoft portal. If you need additional metadata, please contact us for more information.
