Metadata

The metadata of depositar are composed of dataset level metadata and resource level metadata.

Dataset Level

We have organized the metadata at the dataset level into three categories: Basic Information, Spatio-temporal Information, and Management Information.

Basic Information

Field Name Required Description Range
Title No It is recommended to make it brief but specific. E.g. “Taiwan population density by region” is better than “Population figures”. Must be a valid unicode string. The value will be the same as the URL field if the provided value is empty.
URL Yes This URL will be unique across CKAN. Only letters, numbers, - and _ characters are accepted. The URL will be generated automatically when you input the title of the dataset. If there is no letter or number in the title, a random hash will be generated. You can modify the generated URL afterwards. Must not be empty. Must be a valid unicode string.

Data Type Yes The type of the dataset. Fields will be changed according to the data type. Accept multiple values. Use the PARSE.Insight Content-types.
Wikidata Keywords No Search Wikidata items for keywords to describe the dataset as shown below [1]. For labels that are specific to your projects or datasets (eg. grant no.), use Tags instead. The language of keywords may align with the site language setting. Accept multiple values.
Tags No Here you may add tags that will help people find the data and link it with other related data. Tags should be used as labels that are specific to your projects or datasets. Accept multiple values. Must be a valid unicode string, -, _, or . characters. The length limit for the tag is from 1 characters to 100 characters.
