XML Overhead Considered Harmful

July 28th, 2004 by Administrator

Matthias Nicola, Jasmi John: “XML Parsing: A Threat to Database Performance”, 12th Intl. Conference on Information and Knowledge Management, CIKM’2003, New Orleans, November 2003.

This paper, referred to me by Rick Ross, is a fascinating indictment of the inadequacy of XML for large-scale, real-world applications today. Fits in with other work at IBM on this that I saw at WWW2004 in NYC. I’m concerned that there aren’t any other companies than IBM and perhaps DataPower and Sarvega that even hint at working on hardware-assisted XML processing…

Matrics 6-bags in buyout

Matrics Agrees To Acquisiton By Symbol

Yep, another scurrilous bit of RFID news: Matrics gets bought for cash-on-the-barrelhead, $230M on a $38M investment.

The early success of Matrics in selling radio frequency identification (RFID) systems made the five-year-old company one of the Washington area’s more prominent local start-ups. The purchase will give Symbol, which sells bar-code scanning and retail tracking systems, access to an emerging technology that analysts say will become central to the next generation of supply chain management.

Matrics raised a total of $38 million in three rounds of funding from investors including Novak Biddle Venture Partners of Bethesda, the Carlyle Group of the District, and Polaris Venture Partners of Waltham, Mass. Two local investment organizations, WomenAngels.Net and the Dinner Club, also hold stakes in Matrics.

The Decade of Health Information Technology

July 27th, 2004 by Administrator

Last week U.S. Health and Human Services Secretary Tommy Thompson released the first outline of a 10-year plan to build a National Electronic Health Information Infrastructure in the United States.

The report, “The Decade of Health Information Technology: Delivering Consumer-centric and Information-Rich Health Care,” lays out the broad steps needed to achieve always-current, always-available electronic health records (EHR) for Americans. This responds to the call by President Bush this year to achieve Electronic Health Records (EHRs) for most Americans within a decade.

See also: Conference Materials for National Healthcare Information Infrastructure 2004, last week’s summit on the subject.

Secretary Thompson announced a range of actions underway or soon to be launched, which will advance the strategic elements of the Framework:

Establishing a Health Information Technology Leadership Panel to evaluate the urgency of investments and recommend immediate actions — Secretary Thompson will appoint the panel of executives and leaders to assess the costs and benefits of health information technology to industry and society, and develop options for immediate steps by both the public and private sector, based on their individual business experience. The Health Information Technology Leadership Panel will deliver a report on these options to the Secretary no later than fall 2004.

        <u>Private sector certification of health information technology
        products</u> -- EHRs and even specific components such as decision
        support software are unique among clinical tools in that they do
        not need to meet minimal standards to be used to deliver
        care. To increase uptake of EHRs and reduce the risk of
        product implementation failure, the federal government is exploring
        ways to work with the private sector to develop minimal product
        standards for EHR functionality, interoperability, and
        security. A private sector ambulatory EHR certification task
        force is determining the feasibility of certification of EHR
        products based on functionality, security, and
        interoperability.

        <u>Funding community health information exchange demonstrations</u>
        -- HHS&rsquo; Health Resources and Services Administration, with
        the Foundation for eHealth Initiative, announced $2.3 million in
        contracts to support the Connecting Communities for Better Health
        Program. The program is providing seed funds to implement
        health information exchanges, including the formation of regional
        health information organizations.

        <u>Planning the formation of a private interoperability
        consortium</u> -- To begin the process of movement toward a
        national health information network, HHS will issue a Request for
        Information (RFI) this summer inviting responses describing the
        requirements for private sector consortia that would form to plan,
        develop, and operate a health information network. The role
        that HHS could play in facilitating the work of the consortium and
        assisting in identifying the services that the consortium would
        provide will be explored, including the standards to which the
        health information network would adhere in order to ensure that
        public policy goals are executed and that rapid adoption of
        interoperable EHRs is advanced.

        <u>Requiring standards to facilitate electronic prescribing</u> --
        CMS is accelerating publication of a regulation laying out the
        first set of widely adopted e-prescribing standards in preparation
        for the implementation of the new Medicare drug benefit in 2006.
        When the final standards are adopted, Medicare Prescription Drug
        Plan (PDP) Sponsors will be required to offer e-prescribing, which
        will significantly drive adoption across the United States.
        The proposed regulation will be published by CMS this year.

        <u>Establishing a Medicare beneficiary portal</u> -- CMS will
        develop a Medicare Beneficiary Portal, an immediate step in
        improving consumer access to personal and customized health
        information, providing secure health information via the
        Internet. The portal will enable authorized beneficiaries to
        have access to their Medicare information online or by calling
        1-800-MEDICARE. Initially the portal will provide access to
        fee-for-service claims information, which includes claims type,
        dates of service, and procedures. The pilot test for the
        portal will be conducted in Indiana, beginning this year. In
        the near term, CMS plans to expand the portal to include prevention
        information in the form of reminders to beneficiaries to schedule
        their Medicare-covered preventive health care services. CMS
        also plans to work toward providing additional electronic health
        information tools to beneficiaries for their use in improving their
        health.

        <u>Commitment to standards</u> -- A key component of progress in
        interoperable health information is the development of
        interoperability standards and policies. HHS, DoD, and VA
        have endorsed 20 sets of standards to make it easier for
        information to be shared across agencies and to serve as a model
        for the private sector. Additionally, the Public Health Information
        Network (PHIN) and the National Electronic Disease Surveillance
        System (NEDSS), under the leadership of the Centers for Disease
        Control and Prevention (CDC), have made progress in development of
        shared data models, data standards, and controlled vocabularies for
        electronic laboratory reporting and health information
        exchange. With HHS support, Health Level 7 (HL7) has also
        created a functional model and standards for the EHR. </blockquote>

This announcement of a National Healthcare Information Infrastructure brings back memories of the push a decade ago for a National Information Infrastructure (which led to vast investments in building up the public Internet).

Smart Shelves Aren’t

July 23rd, 2004 by Administrator

From the article RFID in Retail Stores: Suggestions for Eliminating Smart Shelves:

In retail stores and other environments, the inability to rapidly locate items is a common problem. Retailers may appear to be out of stock of a product, when in fact the product may be available in the back of the store or may have been placed on the wrong shelf. RFID (radiofrequency identification) technology has been proposed as a means to improve the ability to track inventory and to locate objects. In particular, the use of RFID-tagged objects coupled with smart shelves that include RFID readers has been proposed as a means of efficiently tracking the presence of products in a retail environment. However, the smart shelves that have been demonstrated in public trials have employed numerous expensive RFID readers adapted to read sections of a single shelf, and have required the use of expensive and bulky coaxial cable for each of the readers… In this paper, we propose several alternative systems that may be considered.

The alternatives include techniques for extending RFID signal range, use of active RFID tags with an inherently greater range, a limited number of moving RFID readers that scan RFID tags, and the like.

Teepee

July 22nd, 2004 by Administrator

One of the primary thrusts of our work at CN Labs will be a new kind of internet-scale event notification service: an application-layer router. Just like there’s an IP packet format at the network layer, there ought to be a new standard that unifies the welter of application-layer protocols: smTP, htTP, fTP, nnTP, and more.

TP, a Transfer Protocol, merely provides a best-effort delivery service for named, MIME-typed bags of bits. Rather than using IP addresses, those names are the endpoints that identify multiple services.

If I want a $5 increase in IBM stock price to pop up an alert in my browser, I ought to be able to request something like

“send all messages about http://nyse.com/IBM?delta>5
to javascript://rohits-laptop/window1/alert(’sell!’)”

There’s a lot more to this idea, whether you call it bringing pub/sub to the web, or bringing programmable agents to mail, or some other unification of those messaging middleware modes. Watch this space to see what we can pull together…

Patent wars could stymie RFID

July 22nd, 2004 by Administrator

CRN in Royalties Expected To Increase Cost Of RFID:

The price of electronic tags used to track supply-chain goods could swell if a key standard in the emerging technology, known as RFID, winds up including royalties.

If tag makers absorb the cost, then it will certainly affect already slim margins. Competition is expected to heat up over the next year as the largest manufacturers, such as Texas Instruments Inc., start increasing shipments significantly. Tag prices are expected to drop by about 25 percent by mid to late 2005.
