  1. Getting your metadata using PROC METADATA Edwin J. van Stein Astellas Pharma Global Development Europe

  2. Contents Example of using PROC METADATA to get group memberships for a specific user from metadata

  3. Preparing for output • Output written to physical XML file to later convert to SAS data set • Encoding of XML file specified to prevent problems with strange characters filename outgroups "/sas/user/test/groups.xml" encoding="utf-8";

  4. Setting server connection arguments • SERVER, PORT, USER, PASSWORD and PROTOCOL all default to corresponding system options if not specified • USER and PASSWORD (encoded with PROC PWENCODE) set to user with more rights proc metadata userid="sasadm" password="{sas001}bXkgcGFzc3dvcmQ="

  5. Setting output arguments • Write output to file reference created earlier • Output XML to contain a full header out=outgroups header=full

  6. XML-formatted method call (1) • Tell the metadata server to get objects • From which repository to get objects • Type of objects to get • Specify namespace in='<GetMetadataObjects> <Reposid>$METAREPOSITORY</Reposid> <Type>Person</Type> <NS>SAS</NS>

  7. XML-formatted method call (2) • Set flags so that metadata server performs the correct actions: • Fill a pre-specified template (flag OMI_TEMPLATE=4) • Use an XMLSelect element to filter metadata (flag OMI_XMLSELECT=128) • Get the metadata found (flag OMI_GET_METADATA=256) • Use XMLSelect element case-sensitive (flag OMI_MATCH_CASE=512) <Flags>900</Flags>

  8. XML-formatted method call (3) • Both template and XMLSelect element need to be within <Options> tags • Only want person and group names returned <Options> <Templates> <Person Name=""> <IdentityGroups /> </Person> <IdentityGroup Name=""/> </Templates>

  9. XML-formatted method call (4) • Only return data for persons with a specific name • Close open tags to finalize XML-formatted method call <XMLSelect search="@Name=''Person 1''"/> </Options> </GetMetadataObjects>'

  10. Putting it all together proc metadata userid="sasadm" password="{sas001}bXkgcGFzc3dvcmQ=" out=outgroups header=full in='<GetMetadataObjects> <Reposid>$METAREPOSITORY</Reposid> <Type>Person</Type> <NS>SAS</NS> <Flags>900</Flags> <Options> <Templates> <Person Name=""> <IdentityGroups /> </Person> <IdentityGroup Name=""/> </Templates> <XMLSelect search="@Name=''Person 1''"/> </Options> </GetMetadataObjects>'; run;

  11. The XML output (partial)

  12. Next steps • Explore metadata using 257 as Flag and only setting Type • Conversion to data set using an XML map • Update metadata
