GDS Relation to Standards

The OSI software provided in DCE is based on the following ISO standards:

· X.500/ISO 9594

The CCITT 1988 version (Blue Book), which shares the same text as ISO Directory Standard 9594 (v1) published in 1990.

· ROSE/ACSE/Presentation/Session

ISO 9072 (v1:1989), 8650 (v1:1988), 8649, 8823 (v1:1988), and 8327 (v2:1988) Protocol International Standards. The implementation follows EWOS agreements.

· ASN.1/BER

The ASN.1 compiler accepts ASN.1 syntax conformant to ISO 8824 and generates routines to encode/decode data conformant to ISO 8825 Basic Encoding Rules.

The GDS software provides functional extensions to the standards in the following areas:

· Replication

· Knowledge information Modeling and Administration

· Schema modeling and administration

· Subtree administration

· Caching

· Remote administration

· Security (access control)
