World Wide Web Consortium Issues Three Web Services Recommendations

26.01.2005


Three-Part Solution Leads to Better Web Services Performance



The World Wide Web Consortium (W3C) has published three new Web Services Recommendations: XML-binary Optimized Packaging (XOP), SOAP Message Transmission Optimization Mechanism (MTOM), and Resource Representation SOAP Header Block (RRSHB). These recommendations provides ways to efficiently package and transmit binary data included or referenced in a SOAP 1.2 message.

Web Services Applications Need Effective, Standard Methods for Handling Binary Data


Web Services applications have the primary goal of sharing and using data between applications. This includes an increasingly diverse set of media formats and devices, including large schematics and other graphical files. Examples are as intricate as sharing architectural blueprints between multiple parties, or as simple as sending a photo from a digital camera directly to a printer.

One of the biggest technical and performance issues for Web services occurs when a user or application is handling large binary files. Encoding binary data as XML produces huge files, which absorbs bandwidth and measurably slows down applications. For some devices, it slows down so much that the performance is considered unacceptable.

W3C Devises Three-Part Solution for Better Web Services Performance

W3C’s XML Protocol Working Group has been looking at this issue almost from its inception, while it was developing the first SOAP standard, SOAP 1.2. The newest Recommendations published today work with SOAP 1.2 to address the specific issue of improving Web services performance by providing standard methods and mechanisms for transmitting large binary data.

"By enabling a more efficient way of serialize and transmit a SOAP message (XOP and MTOM), and by sending all the data needed to process the message, even when the data would not be readily available (RRSHB), Web Services have just become faster and more usable, " explained Yves Lafon, W3C Team Contact for the XMLP Working Group.

XOP Allows Efficient Encoding of Binary Data in XML

XML-binary Optimized Packaging (XOP) provides a standard method for applications to include binary data, as is, along with an XML document in a package. As a result, applications need less space to store the data and less bandwidth to transmit it. XOP works at the XML Information Set (Infoset) level, allowing the same abstract representation of a XML document to be serialized in different ways.

MTOM implements XOP, makes SOAP 1.2 faster

The Message Transmission Optimization Mechanism (MTOM) uses the features provided by XOP to address SOAP messages. MTOM defines a "Transmission Optimization" feature that enables SOAP bindings to optimize the transmission and/or the wire format used to transfer a SOAP message. It also defines a concrete implementation of this feature, using HTTP and XOP to send the various binary parts as well as the SOAP message in a MIME envelope, reducing the bandwidth and the time used to encode/decode such data.

RRSHB Gives Applications a Local Short Cut to Resources

The third piece, the Resource Representation SOAP Header Block (RRSHB) functionality allows SOAP message recipients to access cached representations of external resources. This is important, as there may be times when there are either limits to bandwidth or access of files. It gives the recipient the option of using either the original file that may be identified by a URI, or to use a cached copy that accompanies the actual SOAP message. Used with MTOM, it enhance greatly the speed and of processing as the external data is already present when the recipient is starting processing the message.

About the World Wide Web Consortium [W3C]

The W3C was created to lead the Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability. It is an international industry consortium jointly run by the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) in the USA, the European Research Consortium for Informatics and Mathematics (ERCIM) headquartered in France and Keio University in Japan. Services provided by the Consortium include: a repository of information about the World Wide Web for developers and users, and various prototype and sample applications to demonstrate use of new technology. More than 350 organizations are Members of W3C.

Im Focus: The fastest light-driven current source

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.

Graphene is up to the job

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
