-------------------------------------------------------------------------    
                                                                             
1) New Static Standard Values                                                
                                                                             
     PRODUCT_TYPE    {DATA, GEOMETRY, CALIBRATION, DOCUMENT,                 
                     CATALOG, SOFTWARE ANCILLARY, BROWSE}                    
                                                                             
     HEADER object with HEADER_TYPE = TEXT.                                  
                                                                             
     Software change requests have been submitted to the PDS to adopt these  
     changes to the PDS standards but they have not yet been accepted.       
                                                                             
                                                                             
2) Other non-standard practices                                              
                                                                             
     The PDS standards do not specify where to store the required MD5        
     checksum file for a volume.  We have placed it in the root dircetory    
     of the volume with the file name "CHECKSUMS.TXT".  This may be          
     considered invalid by some verifiers.                                   
                                                                             
     PPI has created copies of the PDS catalog files in the EXTRAS/CATALOG   
     directory with a '.TXT' extension. While this makes the files accessible
     to users with the Windows operating system, it is not a standard        
     PDS practice.                                                           
                                                                             
     In order for PPI to be able to track all of the files associated with a 
     data set (data, documents, software ,etc.) and to be able to retrieve   
     them on-demand through our web pages, PPI must include keywords in      
     labels that some might find questionable. In particular, we associate   
     the same start/stop time, targets, mission phases, etc. with a document 
     that are used in the data set. Without these keywords, queries for      
     Cassini INMS data between times A and B would not return the documents  
     or software associated with the data.                                   
                                                                             
3) Known problems and the volumes they affect                                
                                                                             
2023-01-25 - During migration to PDS4 it was noticed that The INMS Packet    
data documentation says it includes five standard data product types,        
outlined in the DS.Cat. However, of these five, only the Housekeeping (HKG)  
Packets have been delivered to PDS and are included in this data set.        
                                                                             
2023-01-25 - During the migration of these data to PDS4 it was discovered    
that corrections were necessary to some of the fields in the                 
DATA/HKG_STRUCT_01.FMT file. The corrections included changes to the number  
of bytes listed in a field and to the field format.  In some cases the field 
format was removed. These corrections were made in the PDS4 labels. The data 
remains unchanged. The PDS3 labels haven not been updated.                   
                                                                             
The following table lists the corrections to the number of bytes in the      
fields listed and format if present and corrected or removed:
