The latest release of View500 contains many changes and enhancements. The new features that have been added to the 6.0 release are listed below.

X.500 Technology
o Internet Directly Mapped Protocol (IDMP)
IDMP is a protocol which provides a TCP/IP transport for DAP, DISP (Shadowing), and DSP (distributed operation) operations.

LDAP Technology
o Simple Authentication and Security Layer (SASL)
A mandatory user authentication scheme for LDAP is the SASL Digest-MD5 mechanism. Instead of the user transmitting their username and password clearly to the LDAP Server, SASL allows only hashed values to be transmitted.

XML Enabled Directory (XED)
View500 Version 6.0 is the only directory available that supports XED.
The XML Enabled Directory is a newly developed standard, which defines a framework that leverages off existing technology such as ASN.1, XML, X.500 and LDAP.
Some of the features available in version 6.0, due to XED, include:
Robust XML Encoding Rules (RXER)- RXER is an XML based encoding rule. Instead of using an unreadable binary encoding rule (such as BER), the directory is now able to encode data using RXER, a text based encoding rule.

XIDMP
Currently, IDMP can be used to send DAP, DSP, and DISP PDU's over a TCP/IP connection. IDMP states that these PDU's must be encoded using the Basic Encoding Rules (BER). XIDMP allows the IDMP PDU's to be transmitted in an XML based encoding, such as RXER.

XML Lightweight Directory Access Protocol (XLDAP)
XLDAP is semantically equivalant to LDAP, with the major difference being the encoding rule used to encode the PDU. RXER is used to encode XLDAP PDU's.
XED defines two transport mechanisms in which XLDAP messages can be transmitted over, XLDAP over TCP/IP and XLDAP over SOAP 1.1.
View500 will be supporting both of these mechanisms in the next release.

Extended LDAP Data Interchange Format (ELDIF)
The LDIF specification imposes restrictions that result in XML encoded values being converted into an unreadable Base64 format within LDIF dumps.
ELDIF extends the current LDIF specification to make allowances for XML encoded values so their human readable encoding is retained.

For more information on XED, including the set of standards which define the XED framework, visit the XED website, which can be found in the Links section.

Free View500
A restricted, yet freely downloadable, version of View500. Whilst restricted enough to be inadequate for a commercial environment, this cutdown version of View500 will allow potential customers to use some of our new XED based protocols like XLDAP.
