Typically, <OnlineAccessURLs> in the metadata is populated with correct links by LPDAAC during Cumulus ingestion.
LPDAAC confirmed that Cumulus workflow appends individual urls (and does not overwrite). Therefore, if we include the https and s3 links to the HLS Fmask layer under <OnlineAccessURL> in the cmr.xml metadata file when we deliver the HLS granule to LPDAAC, these links should be retained during Cumulus ingestion.
The structure of the <URL> field is https://data.lpdaac.earthdatacloud.nasa.gov/lp-prod-protected/{collection_shortname}/{granule_id}/{granule_id}.Fmask.tif
and s3://lp-prod-protected/{collection_shortname}/{granule_id}/{granule_id}.Fmask.tif
collection_shortname either being HLSL30.020 or HLSS30.020.
For example, metadata for L30 VI granule HLS-VI.L30.T56JMM.2024349T233644.v2.0 that we generate should include

@junchangju Please review the <URLDescription> fields above and confirm that this is acceptable.
As requested by @junchangju , we need to include HLS Fmask information in HLS-VI granule metadata. After discussion with LPDAAC, it was recommended to include a link to Fmask layer in the
<OnlineAccessURLs>
attribute in the metadata.Typically,
<OnlineAccessURLs>
in the metadata is populated with correct links by LPDAAC during Cumulus ingestion.LPDAAC confirmed that Cumulus workflow appends individual urls (and does not overwrite). Therefore, if we include the
https
ands3
links to the HLS Fmask layer under<OnlineAccessURL>
in thecmr.xml
metadata file when we deliver the HLS granule to LPDAAC, these links should be retained during Cumulus ingestion.The structure of the
<URL>
field ishttps://data.lpdaac.earthdatacloud.nasa.gov/lp-prod-protected/{collection_shortname}/{granule_id}/{granule_id}.Fmask.tif
and
s3://lp-prod-protected/{collection_shortname}/{granule_id}/{granule_id}.Fmask.tif
