options metaserver="a123.us.company.com"
	metaport=8561
	metauser="myid"
	metapass="mypassword"
	metarepository="myrepos";

data _null_;
    length attr $256
    	   value $256;
    rc=1;
    n=1;
    do while(rc>0);

        /* Walk through all the attributes on this machine object. */

        rc=metadata_getnatr("omsobj:Machine?@Name='bluedog'",
                            n,
                            attr,
                            value);

        if (rc>0) then put n= attr= value=;

        n=n+1;

    end;
run;

Example 2: Using a Repository URI

options metaserver="a123.us.company.com"
	metaport=8561
	metauser="myid"

data _null_;
    length id $20
	   type $256
	   attr $256
	   value $256;
	   
    rc=metadata_resolve("omsobj:RepositoryBase?@Name='myrepos'",type,id);

    put rc=;
    put id=;
    put type=;
    n=1;
    rc=1;
    do while(rc>=0);

        rc=metadata_getnatr("omsobj:RepositoryBase?@Name='myrepos'",n,attr,value);
        if (rc>=0) then put attr= value=;
        n=n+1;
