Dataset lost isPartOf metadata

[FuhuXia]

Records containing isPartOf metadata lost this property after the dataset is created on catalog-next. This info is crucial to build collection relationship.

How to reproduce

This GSA json source has "isPartOf": "GSA-2015-09-14-02".

The corresponding dataset on catalog-next does not contain this propery in the extras fields.

Expected behavior

See this in the package_show result.

"extras": [
{
"key": "isPartOf",
"value": "GSA-2015-09-14-02"
},

Actual behavior

No such property in package_show result.
