Set my token

export token="<token-goes-here>"

Create a 200MB file:

dd if=/dev/urandom of=200MB-file.txt bs=1M count=200

Write the system metadata file to cjones.10000.1.sysmeta.xml with:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns3:systemMetadata xmlns:ns2="http://ns.dataone.org/service/types/v1" xmlns:ns3="http://ns.dataone.org/service/types/v2.0">
    <serialVersion>1</serialVersion>
    <identifier>cjones.10000.1</identifier>
    <formatId>text/plain</formatId>
    <size>209715200</size>
    <checksum algorithm="MD5">9125b60f354f9d74311ddda715f237bb</checksum>
    <submitter>http://orcid.org/0000-0002-8121-2341</submitter>
    <rightsHolder>http://orcid.org/0000-0002-8121-2341</rightsHolder>
    <fileName>200MB-file.txt</fileName>
</ns3:systemMetadata>

Upload the file

    -X POST \
    -H "Authorization: Bearer ${token}" \
    -F "pid=cjones.10000.1" \

    -F "object=@200MB-file.txt" \
    "https://test.arcticdata.io/metacat/d1/mn/v2/object"
