json vs xml metadata main difference

[Danny-dK]

I received a question on json vs xml format for metadata. Within Yoda, there was a switch from xml to json. What is the main difference or benefit to use json formats? Is there for example a switch to json formats for metadata happening world-wide, or was it more practicality within Yoda. When dealing with metadata outside of Yoda, would there be a preference to use one format over the other?

There are several benefits for using JSON for our metadata:

• JSON is somewhat more human readable then XML
• DataCite introduced DataCite JSON: https://blog.datacite.org/introducing-datacite-json/
• All the libraries we use support JSON, switching from XML to JSON removed the need to transform between the two formats
• We can use JSON schema (https://json-schema.org/)
