-Abstract
-
- This document defines a syntax schema element for the Lightweight
- Directory Access Protocol ([LDAP]) which is used to hold a Change
- Sequence Number (CSN). In general, a change sequence number
- represents the place and time that a directory entity was changed. It
- may be used by various attributes for various LDAP replication, and
- synchronization applications.

-1. Introduction
-
- A number of technologies have been documented, implemented and
- experimented with which in one way or another seek to replicate, or
- synchronize directory data. A common need among these technologies is
- to determine which of two copies of an element represents the latest
- or most authoritative data. Part of meeting this need involves
- associating a change sequence number to an element copy at the time
- of an update to that element. When replication or synchronization
- occurs, the change sequence numbers associated with directory
- elements can be used to decide which element's data will be copied to
- the other element(s).
-
-
-2. Conventions
-
- The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
- "SHOULD", "SHOULD NOT", "RECOMMENDED", and "MAY" in this document are
- to be interpreted as described in [Keyword].
-
- The General Considerations in Section 3.1 of [Syntaxes] apply to the
- syntax definition in this document.
-
- The terms "directory element" and "element" refer to data held in a
- directory and may apply to an attribute value, attribute, entry, or
- any other identifiable directory entity.
-
-
-3. Syntaxes
-
-3.1 ChangeSequenceNumber Syntax
-
- A value of the ChangeSequenceNumber syntax is the time of a change
- along with a replicaID which represents the Directory System Agent
- (DSA) holding the element when it was changed. There are also two
- sequence numbers used to disambiguate directory entities that are
- changed at the same time and place.
-
- The Abstract Syntax Notation One ([ASN.1]) type corresponding to this
- syntax is defined as follows:
-
- ChangeSequenceNumber ::= SEQUENCE {
- time GeneralizedTime,
-
-Sermersheim Internet-Draft - Expires Jun 2004 Page 2 \f
- LDAP Change Sequence Number
-
- timeCount INTEGER (0 .. MaxInt),
- replicaID UTF8String,
- changeCount INTEGER (0 .. MaxInt)}
-
- MaxInt INTEGER ::= 2147483647 -- (2^^31 - 1) --
-
- GeneralizedTime is defined in [ASN.1]. Local time without a
- differential SHALL NOT be used.
-
- UTF8String is defined below.
-
- The LDAP-specific encoding of a value of this syntax is the Generic
- String Encoding Rules ([GSER]) encoding of the ASN.1 type.
-
- Example:
- { time "196701160315-0700",
- timeCount 0,
- replicaID "DSA666",
- changeCount 1 }
-
- The following is an LDAP syntax description [RFC2252] suitable for
- publication in the subschema.
-
- ( IANA-ASSIGNED-OID.1 DESC 'ChangeSequenceNumber' )
-
-
-3.2 UTF8String
-
- The UTF8String syntax is used to express a string of characters from
- the [ISO10646] character set (a superset of [Unicode]), encoded
- following the [UTF-8] algorithm. Note that Unicode characters U+0000
- through U+007F are the same as ASCII 0 through 127, respectively, and
- have the same single octet UTF-8 encoding. Other Unicode characters
- have a multiple octet UTF-8 encoding.
-
- UTF8String::= OCTET STRING -- UTF-8 encoded,
- -- [ISO10646] characters
-
- The LDAP-specific encoding of a value of this syntax are the UTF-8
- characters themselves.
-
- The following is an LDAP syntax description [RFC2252] suitable for
- publication in the subschema.
-
- ( IANA-ASSIGNED-OID.2 DESC 'UTF8String')
-
-
-4. Matching Rules
-
-
-4.1 changeSequenceNumberMatch Matching Rule
-
- The changeSequenceNumberMatch rule compares an assertion value of the
- ChangeSequenceNumber syntax to a value of a syntax (e.g the
-
-Sermersheim Internet-Draft - Expires Jun 2004 Page 3 \f
- LDAP Change Sequence Number
-
- ChangeSequenceNumber syntax) whose corresponding ASN.1 type is
- ChangeSequenceNumber.
-
- The rule evaluates to TRUE if and only if each of the components of
- the two values evaluate to true using the following rules:
- - The time component uses generalizedTimeMatch.
- - The timeCount and changeCount components use integerMatch.
- - The replicaID component uses utf8CodePointMatch.
-
- The following is a LDAP matching rule description [RFC2252] suitable
- for publication in the subschema.
-
- ( IANA-ASSIGNED-OID.3 NAME changeSequenceNumberMatch
- SYNTAX IANA-ASSIGNED-OID.1 )
-
-
-4.2 utf8CodePointMatch Matching Rule
-
- The utf8CodePointMatch rule compares an assertion value of the
- UTF8String syntax to a value of a syntax (e.g the UTF8String syntax)
- whose corresponding ASN.1 type is UTF8String. The rule evaluates to
- TRUE if and only if the code points [Unicode] of each of the
- characters is equal.
-
- The following is a LDAP matching rule description [RFC2252] suitable
- for publication in the subschema.
-
- ( IANA-ASSIGNED-OID.4 NAME utf8CodePointMatch
- SYNTAX IANA-ASSIGNED-OID.2 )
-
-
-4.3 changeSequenceNumberOrderingMatch Matching Rule
-
- The changeSequenceNumberOrderingMatch rule compares the
- ChangeSequenceNumber ordering of an assertion value of the
- ChangeSequenceNumber syntax to a value of a syntax (e.g the
- ChangeSequenceNumber syntax) whose corresponding ASN.1 type is
- ChangeSequenceNumber.
-
- The rule evaluates to TRUE if and only if each of the components of
- the two values evaluate to true using the following rules:
- - The time component uses GeneralizedTimeOrderingMatch.
- - The timeCount and changeCount components use integerOrderingMatch.
- - The replicaID component uses utf8CodePointOrderingMatch.
-
- The following is a LDAP matching rule description [RFC2252] suitable
- for publication in the subschema.
-
- ( IANA-ASSIGNED-OID.5 NAME changeSequenceNumberOrderingMatch
- SYNTAX SYNTAX IANA-ASSIGNED-OID.1 )
-
-
-4.4 utf8CodePointOrderingMatch Matching Rule
-
-
-Sermersheim Internet-Draft - Expires Jun 2004 Page 4 \f
- LDAP Change Sequence Number
-
- The utf8CodePointOrderingMatch rule compares the ordering of an
- assertion value of the UTF8String syntax to a stored value of a
- syntax (e.g the UTF8String syntax) whose corresponding ASN.1 type is
- UTF8String.
-
- The rule evaluates to TRUE if, and only if, in the code point
- collation order, the stored value character string appears earlier
- than the assertion value character string, i.e., the stored value is
- "less than" the assertion value.
-
- The following is a LDAP matching rule description [RFC2252] suitable
- for publication in the subschema.

+
+3. Syntaxes
+
+3.1. ChangeSequenceNumber Syntax
+
+ A value of the ChangeSequenceNumber syntax is the time of a change
+ along with a replicaID which represents the Directory System Agent
+ (DSA) holding the element when it was changed. There are also two
+ sequence numbers used to disambiguate directory entities that are
+ changed at the same time and place.
+
+ The Abstract Syntax Notation One (ASN.1)[X680] type corresponding to
+ this syntax is defined as follows:
+
+ ChangeSequenceNumber ::= SEQUENCE {
+
+ time GeneralizedTime,
+
+ timeCount INTEGER (0 .. MaxInt),
+
+ replicaID UTF8String,
+
+ changeCount INTEGER (0 .. MaxInt)}
+
+ MaxInt INTEGER ::= 2147483647 -- (2^^31 - 1) --
+
+ GeneralizedTime is defined in [X680]. Local time without a
+ differential SHALL NOT be used.
+
+ UTF8String is defined below.
+
+ The LDAP-specific encoding of a value of this syntax is the Generic
+ String Encoding Rules (GSER)[RFC3641] encoding of the ASN.1 type.
+
+ Example:
+
+ { time "196701160315-0700",
+
+ timeCount 0,
+
+ replicaID "DSA666",
+
+ changeCount 1 }
+
+ The following is an LDAP syntax description [RFC2252] suitable for
+ publication in the subschema.

+\f
+Internet-Draft LDAP CSN February 2005
+
+
+3.2. UTF8String
+
+ The UTF8String syntax is used to express a string of characters from
+ the [ISO.10646-1.1993] character set (a superset of [Unicode]),
+ encoded following the [UTF-8] algorithm. Note that Unicode
+ characters U+0000 through U+007F are the same as ASCII 0 through 127,
+ respectively, and have the same single octet UTF-8 encoding. Other
+ Unicode characters have a multiple octet UTF-8 encoding.
+
+ UTF8String::= OCTET STRING -- UTF-8 encoded,
+
+ -- [ISO10646] characters
+
+ The LDAP-specific encoding of a value of this syntax are the UTF-8
+ encoded characters themselves.

+4. Matching Rules
+
+4.1. changeSequenceNumberMatch Matching Rule
+
+ The changeSequenceNumberMatch rule compares an assertion value of the
+ ChangeSequenceNumber syntax to a value of a syntax (e.g the
+ ChangeSequenceNumber syntax) whose corresponding ASN.1 type is
+ ChangeSequenceNumber.
+
+ The rule evaluates to TRUE if and only if each of the components of
+ the two values evaluate to TRUE using the following rules:
+
+ o The time component uses generalizedTimeMatch.
+
+ o The timeCount and changeCount components use integerMatch.
+
+ o The replicaID component uses utf8CodePointMatch.
+
+ The following is a LDAP matching rule description [RFC2252] suitable
+ for publication in the subschema.
+
+ ( IANA-ASSIGNED-OID.3 NAME changeSequenceNumberMatch SYNTAX IANA-
+ ASSIGNED-OID.1 )
+
+4.2. utf8CodePointMatch Matching Rule
+
+ The utf8CodePointMatch rule compares an assertion value of the
+ UTF8String syntax to a value of a syntax (e.g the UTF8String syntax)
+ whose corresponding ASN.1 type is UTF8String. The rule evaluates to
+ TRUE if and only if the code points [Unicode] of each of the
+ characters is equal.
+
+ The following is a LDAP matching rule description [RFC2252] suitable
+ for publication in the subschema.
+
+ ( IANA-ASSIGNED-OID.4 NAME utf8CodePointMatch SYNTAX IANA-ASSIGNED-
+ OID.2 )
+
+4.3. changeSequenceNumberOrderingMatch Matching Rule
+
+ The changeSequenceNumberOrderingMatch rule compares the
+ ChangeSequenceNumber ordering of an assertion value of the
+ ChangeSequenceNumber syntax to a value of a syntax (e.g the
+ ChangeSequenceNumber syntax) whose corresponding ASN.1 type is
+ ChangeSequenceNumber.
+
+ When evaluating ChangeSequenceNumber values for ordering, the
+ components are evaluated in this order: time, timeCount, replicaID,
+
+
+
+Sermersheim & Chu Expires August 5, 2005 [Page 7]
+\f
+Internet-Draft LDAP CSN February 2005
+
+
+ changeCount. If a component evaluates to TRUE using the appropriate
+ ordering matching rule specified below, then the rule evaluates to
+ TRUE. Otherwise if the component evaluates to TRUE using the
+ equality matching rule specified below, the next component is
+ evaluated. Otherwise the changeSequenceNumberOrderingMatch rule
+ evaluates to FALSE or Undefined as appropriate.
+
+ o The time components of the two values are evaluated for ordering
+ using GeneralizedTimeOrderingMatch, and evaluated for equality
+ using GeneralizedTimeMatch.
+
+ o The timeCount and changeCount components of the two values are
+ evaluated for ordering using integerOrderingMatch, and evaluated
+ for equality using integerMatch.
+
+ o The replicaID components of the two values are evaluated for
+ ordering using utf8CodePointOrderingMatch and evaluated for
+ equality using utf8CodePointMatch.

+
+4.4. utf8CodePointOrderingMatch Matching Rule
+
+ The utf8CodePointOrderingMatch rule compares the ordering of an
+ assertion value of the UTF8String syntax to a stored value of a
+ syntax (e.g. the UTF8String syntax) whose corresponding ASN.1 type is
+ UTF8String.
+
+ The rule evaluates to TRUE if, and only if, in the code point
