• SOAP 1.1 Implementation - this new release includes a wide range of new SOAP features, bringing it up to date with the most recent developments of this rapidly evolving technology :

    • Flexibility in configuring SOAP access points using a WEB based user interface allowing exposure of selected stored procedures as SOAP services. These procedures may be local or linked from any 3rd party databases. The effective privileges for running SOAP exposed procedures can also be set at the access point level.

    • Improved SOAP to Virtuoso/PL Language Binding allowing the receiving and returning of arbitrarily complex arrays and structures, using XML Schema to describe the mapping of Virtuoso internal types to precisely match specification expressed in XML Schema.

    • Automated generation of WSDL descriptions of SOAP access points - Simple procedure parameter lists map automatically to SOAP types described in XML Schema. For complex types, procedures can be annotated with explicit references to XML Schema types. Thus the developer has complete control over the presentation of web services.

    • Import of WSDL descriptions of outside web services. Virtuoso automatically generates Virtuoso/PL wrappers based on an outside WSDL file, making all its services transparently callable as stored procedures from Virtuoso/PL.

    • Virtuoso's SOAP client and server implementations pass the SOAP Interop tests levels 1, 2 and most of 3.

    • Virtuoso Service Module for XML (VSMX) is a mechanism provided by Virtuoso for testing SOAP messages by automatically generating a test page - a VSMX file - that has the extension .vsmx. The VSMX file is generated at the same time as the WSDL file is generated, giving instant access to your SOAP messages to test they perform as expected. Web Service developers would use VSMX to forego the test bed creation step in light of automatic test page generation. Project managers can easily keep track of their developers progress by checking the test page periodically.

  • XSLT 1.1 Implementation - support for the XSLT 1.1 Draft Specification has been added.

  • Exposure of Stored Procedures as Web Services - Stored procedures can be exposed as SOAP services very simply from Virtuoso, whether the procedures are native Virtuoso or on remote data sources. This powerful ability means that any database servers already existing within an organization can easily become a component in an eBusiness solution using Virtuoso.

  • XML Schema - contains a built-in XML Schema 2001 validator. This is accessible from Virtuoso/PL as a function and is used for SOAP and XQuery where appropriate.

  • XML Templates - Virtuoso XML templates allow execution of SQL/XML queries over HTTP to obtain an XML document in response and/or perform some operation in the database using updategrams. The XML Template file can be stored either on the file system, WebDAV repository or stored on another HTTP server being referenced by a URL parameter.

  • XQuery - Virtuoso provides support for the XQuery 1.0 XML Query Language specification. This specification is currently in the working draft stage at the W3C XML Query Working Group working in collaboration with the W3C XSL Working Group.

  • Web DAV - support for redirection of resources, using the Web DAV Redirect Reference Resource Protocol draft 02 specification.

  • Remote Stored Procedures - Stored Procedures located in remote databases can now be linked into the Virtuoso Server in the same manner as you would link in tables or views. This enables remote stored procedures to be readily and easily exposed as WEB Services.

  • OLE DB Provider - native OLE DB Provider is now available allowing direct connection from ADO and .Net applications.

  • JDBC Driver - enhanced JDBC support with full compliance with JDBC J2EE standard.

  • Free Text - The full text indexing capability has been extended, giving the developer flexibility in choosing complex, multi-part document id's for application specific sorting of hits, efficient storage of secondary, non-free text data in the free text index for best retrieval performance, options for restarting searches at a specific hit, ascending and descending orders of document id's and more.

  • Free Text Triggers - The free text triggers system allows persisting free text queries into a table, so that when a free text index is updated, the incoming data gets automatically matched against these persisted criteria, generating hits as the index is updated. This allows very high performance filtering of fast changing text data, e.g. news feeds without having to run periodic query batches and is ideal for creating personalized information feeds.

  • LDAP - support for the Lightweight Directory Access Protocol (LDAP) protocol for accessing online directory services.

  • Enhanced Flexibility of Database and VDB security - New SQL hooks allow the developer to customize password checking at the time of accepting SQL connections into the server. Another hook allows an application to dynamically determine the login/password to use when connecting to a remote database. These hooks make it possible for example to consult an LDAP directory for user information when validating logins.

  • File DSN support - with the ability to describe a database connection in a simple disk file, Virtuoso becomes more portable, and no longer dependent on per-machine DSNs. If you use file DSNs you can move your database file and your connection information to any computer that has the appropriate drivers installed.

  • Scrollable cursor support in the stored Procedure Language (PL) - Virtuoso PL now allows you direct access to all ODBC standard features of scrollable cursors through PL routines. ODBC calls are still supported but you have a choice of which level to write your code.
