Retrieve metadata in irods HTTP API

[e.v.wi...@gmail.com]

HI,

Maybe I overlooked it, but I could not find a way to query or retrieve metadata through the iRODS HTTP API. It seems a bit inconsistent that there is an endpoint for adding and removing metadata, but not for retrieving. Is it really not in there, or am I missing something?

Regards,

Hi Erwin,

Not overlooked - getting metadata would be done through the genquery
interface...

https://github.com/irods/irods_client_http_api/blob/main/API.md#execute_genquery

"select META_DATA_ATTR_NAME, META_DATA_ATTR_VALUE,
META_DATA_ATTR_UNITS where DATA_NAME = 'file1.txt'"

would give you the AVUs for all data objects named file1.txt.
