Overview

Metadata is data [information] that provides information about other data. Information such as the data source, date of the dataset, how the dataset was created, how it can be shared, and other details about its use. The creation of metadata is vital to ensure that the copyright of the data are preserved and any specifics on the use of the data are maintained. Everyone loves having lots of metadata attached to their datasets, but creating and maintaining this metadata is often too burdensome during field operations. about data or data that defines or describes other data. Metadata is additional information or documentation about your dataset that will make it easier for others to understand and put your data into context. Good metadata is critical in humanitarian response as datasets are often incomplete or the “best available” and have limitations or discrepancies. Noting the issues related to the datasets allows others to understand how and if they can use the datasets.
When metadata is included with a dataset:
It improves understanding of the dataset (reduces questions and confusion of its use and history)
Increases credibility/reliability of data
Provides transparency about data that is not complete or not perfect (sets expectations and can provide the purpose of the dataset)
It can increase interest by others who may have data you are missing
It can improve the discoverability on HDX or other data sharing sites. HDX recommends the following information.

When developing metadata for Common Operational Datasets (or any dataset that is shared on HDX) consider where it will be located:

To balance the need for metadata against the burden of creating and maintaining it, OCHA recommends a 3-tiered system of metadata options:
Tier 1: Emergency Metadata
Tier 2: Basic Metadata
Tier 3: Full Metadata

Description
...
Les métadonnées sont des données [informations] fournissant des informations sur d’autres données. Des informations telles que : la source de données, la date de l’ensemble de données, la façon dont l’ensemble de données peut être partagé, mais également d’autres détails sur leurs utilisations. La création de métadonnées est fondamentale pour s’assurer que le droit d’auteur des données est préservé et que toutes les particularités de l’utilisation des données sont respectées. Tout le monde apprécie le fait d'avoir beaucoup de métadonnées associées à leurs ensembles de données, cependant, la création et la maintenance de ces métadonnées sont généralement très fastidieuses pendant les opérations sur le terrain.
...
Lors de l’élaboration des métadonnées pour les ensembles de données opérationnelles communes (ou tout autre ensemble de données partagé sur HDX), tenez compte de l’endroit où il sera situé :
Sur HDX | Dans/avec l'ensemble de données | Service Web COD-AB |
|---|---|---|

Pour équilibrer le besoin de métadonnées et «la complexité de leur création et mise à jour, OCHA recommande un système à trois niveaux d’option pour les métadonnées :
Niveau (Tier) 1 : Métadonnées d’urgence
Niveau (Tier) 2 : Métadonnées de base
Niveau (Tier) 3 : Métadonnées complètes
Niveau 1 : Métadonnées d’urgence
