Rong, Thanks for the clarification, I was assuming the error was coming from the value of the hashtable rather than hashtable itself.
The XML schema contains the following: <xs:element name="original_author" type="StringDictionaryItem" maxOccurs="unbounded"/> This seems to reflect the spec (i.e 1..*). It may be possible that the Ocean parser is not currently validating against the schema but I would be interested to see the archetype causing this issue to test this.

Hi Adam, Heath The attribute in question, original_author is an attribute of Class RESOURCE_DESCRIPTION from rm.common.resource package. According to the specs (common_im.pdf), the type is Hash<String,String> NOT a string and the invariant on it is "Original_author_valid: original_author /= Void and then not original_author.is_empty". The Java implementation (see below) of this invariant is, I believe, faithful interpretation of the specs. if (originalAuthor == null || originalAuthor.size() == 0 ) { throw new IllegalArgumentException("null or empty originalAuthor"); } The thing I am not sure here is the XML schema. If the schema is not compliant with the RM specs, perhaps the schema should be updated so the parsing code generated from schema can catch errors like this, thoughts?

Looking at the AOM, the originalAuthor is a required attribute and this is reflected in the Resource.xsd. However apart from the list being non-empty, I see no other invariant to that states that the value of the originalAuthor item cannot be an empty string. Therefore I would suggest that the Java IllegalArgumentException "null or empty originalAuthor" is too tight. A "not null" invariant seems reasonable. However, not being a member of the java implementation I will leave that to them to decide what to do here. If there is an issue with the Ocean XML output please feel free to contact me directly.
