Open Meta Tools Make It Big

Morgahastu writes "Byte.com has a great article about open meta tools and open software in general: "After more than 10 years of open-software development in the scientific community, open software now holds a preeminent place in the operation of the computing community. The three products I have written about simply scratch the surface of the powerful tools available. OpenLDAP and OAI both enable a wide variety of sharing and automated access.""

      The OAI spec mandates that data providers support unqualified Dublin Core, but you can provide any other metadata format you want in addition to Dublin Core (as long as there's an XML schema defining the format available). So, both
      PRISM and SCORM should work with OAI (although
      you might have to whip up an XML schema for
      PRISM -- I'm not sure there's an official one in the works). Various communities are looking at OAI for exchanging non-Dublin Core metadata; librarians are looking at it for exchanging MARC data and other forms of metadata (such as the MODS and METS formats). I'd be surprised if someone isn't already trying to do an OAI/SCORM project.

      It would maybe not make sense directly. However, set an LDAP system as a front-end to the database, and you can access all the data you need in a standard way; connect several library databases into one homogenous virtual database and so on.

      Maybe (and this is blue-sky territory) have a personal LDPA server that in turn accesses all the data you have access to - search for 'Turing', and you will get Google links, references to his papers (with abstracts, and maybe full-text), and information on what publications are available at your local library, through inter-library loans, and what they would cost you to buy at any of several online bookstores.

      The Lightweight part of LDAP means that it is optimised for reading, and does not expect to be written to very much. Databases, on the other hand, could be considered heavyweight because, with transactions, they can guarantee the accuracy of the data.

      You cannot run an airline reservation system on LDAP. If I update LDAP information, the next few readers might get stale data.

      LDAP is thus lighter on resources, and, IMHO, would be a better tool for a library index.

    It has come to my attention that the entire Microsoft community is a hotbed of so called 'alternative sexuality,' which includes anything from hedonistic orgies to homosexuality to pedophilia.

    What better way of demonstrating this than by looking at the hidden messages contained within the names of some of Windows' most outspoken advocates:

    • William Henry Gates is an anagram of 'Anal Might, we're sly,' clearly referring to the 'Gay Power' movement as well as pointing out the cleverness of his own anagram. Note also that the familiar 'Bill Gates' is an anagram of 'I get balls.'
    • Steve Ballmer needs no anagram - the request 'Ball Me' is clearly contained in his name. Obviously he is 'out of the closet.'
    • Craig Mundi, unbeknownst to most, added the 'e' onto his last name to cover up the anagram 'I cum in drag' which shows beyond the shadow of a doubt that he is a queer transvestite.


    The incredible faggotry of the Microsoft community can also be seen in its software products. Internet Explorer sounds harmless enough, but on the Microsoft 'campus' (obviously a reference to the colleges and universities where these perverts first practiced their filthy homosexual behavior) it is referred to as 'InterNUT Explorer' and refers to a device used to tickle the sensitive area of the scrotum between the testicles.

    Microsoft Exchange clearly refers to the 'exchange of bodily fluids' which is of course how these depraved specimens of humanity plan to transmit the AIDS virus to the rest of the world.

    As far as William 'Homo' Gates goes, that filthy fudge-packer was actually quoted in Time magazine as saying the following: "Just in terms of allocation of time resources, religion is not very efficient. There's alot more I could be doing on a Sunday morning."

    And this isn't a made up troll bullshit either! He actually stated this tripe, which makes it obvious that he is trying to politely say that he's a God-forsaken homo slut!

    Furthermore, Mr. Gaytes has been quoted as saying "There won't be anything we won't say to people to try and convince them that our way is the way to go," proving that the fag sympathisers are wrong, and these perverts really do want to recruit our fine young heterosexual boys and turn them into flaming queers like themselves.

    Speaking about 'flaming,' who better to point out as a filthy chutney ferret than Microsoft's own self-confessed homo pimp Craig Mundi(e). He has already confessed, nay boasted of his status as a gay sex pusher. To quote from an interview
    with Planet IT:

    "One of the things we want to do and recognize that there's a market for [is] selling people services on a contract or recurring revenue basis, as opposed to traditional royalty bearing for the one-time shipment"

    Selling 'people services,' eh? Is this why you were touching your penis in the cinema, Craig? And charging the other boys money to touch it too?

    We should also point out that Craig has been referred to as 'Microsoft's resident Gasbag.' Is there any more doubt? For those fortunate few who aren't aware of the list of homosexual terminology found inside the Windows 'Shared Sauce Philosophy,' a 'Gasbag' is a pervert who gains sexual gratification from having a thin straw inserted into his urethra (or to use the common parlance, 'piss-pipe'), then his homosexual lover blows firmly down the straw to inflate his scrotum. This is, of course, when he's not busy violating the dignity and copyright of small software companies
    by gathering together their utilities and combining them en masse into the next version of Windows to further his twisted and manipulative agenda of world domination.

    Sick, disgusting antichristian perverts, the lot of them.

    In addition, many of the Windows error messages (an 'error message' is the most common way the faggots communicate) are full of homsexual slang. 'This program has performed an illegal operation' is their way of advertising that they have been engaged in the vile practice of sodomy. 'A fatal exception has occurred' is obviously stating that AIDS has claimed the life of another dick sucker. Rather than recognizing that the fag was properly punished for his deviant behavior, Microsoft-loving queers suggests giving a 'three finger salute' when this happens. Needless to say, this gesture of sympathy involves inserting three fingers into your rectum and farting loudly.

    Another group of Windows anal violators, going by the code name 'Windows Update' ( ) encourage users to 'download' (receive into their rectums) 'service packs' (also known as 'fudge packs') and 'device drivers' (some sort of mechanical penis, I suspect).

    The fags have even invented special tools to aid their faggotry! The program Outlook Express is an anagram of 'Super Sex Tool OK,' which obviously is an endorsement of all kinds of sick behaviors. And obviously PowerPoint is a motorized device for penetrating a virgin anal sphincter.

    More evidence is in the fact that Windows users say how much they love 'My Computer.' They sometimes go so far as to say that all new Windows users (who are in fact just innocent heterosexuals indoctrinated by the gay propaganda) should use this icon. The correct spelling of this phrase can again be found in the 'Shared Sauce Philosophy.'
    It is actually 'My cum pooter,' an endearing term used by dominant fags for their queer-love
    partners. In no other system do users boast of frequently having their rectums pumped full of semen, then farting to expel the jism in a fine mist.

    Other areas of the system also show Windows' inherit gayness. For example, people are often told of the 'C: prompt' but how many innocent heterosexual Linux users know what this actually means. The answer is shocking: Seek colon, prompt - a request given by a faggot to his partner when he desires immediate, deep penetration of his ass!

    Even the icon 'Recycle Bin' originally referred to a homosexual practice. 'Recycle Bin' of course refers to the popular gay practice of using a young boy's anus as a repository for semen. Shortly after one disgusting faggot spews a load of hot jism into the boy's ass, another queer will lick the 'Shared Sauce' back out of the 'Recycle Bin'.

    To summarise: Windows is gay. 'Microsoft' is the graphical description of the state of a fag's penis after he has spewed a load of hot sperm into his gay lover's mouth or rectum. And .NET is for hermaphrodites and disabled 'stumpers.'

    Projects which implemented Z39.50 for the purposes of interoperability are ONE and ONE-2, EUROPAGATE, Desire and Desire II, DECOMATE and DECOMATE II, and Renardus just to touch the surface. Don't forget OHIOLINK...

    Another other older, but interesting, metadata activity have been SGML MARC, and the corresponding XML MARC.

    Those that are interested in more detailed reading can check out the Nordic Metadata Project, Nordic Metadata Project II, which studied the practical implications of cross browsing multiple databases and especially the use of Dublic Core. Even if you get agreement on the protocol and data standard, cross searching's not as easy as it sounds. One of the tools is the Dublin Core Metadata Temple (get it while you still can).

    The BYTE article was exciting to see again and could have benefited further from pointing out the relative ease of use of Dublic Core. OAI uses unqualified Dublic Core, SAFARI uses qualified Dublin Core to create an up to date index over academic research in Sweden. Shoot, since it already uses some META tags, you could even tweak htdig to use Dublic Core on your own site for those high precision searches.

    With the interest in structured data (XML?) maybe well see some sites serving up not just HTML with Dublic Core, but maybe even Docbook or even TEI / TEI Lite. There are great tools for converting from Docbook to HTML, PDF, RTF, etc. and AbiWord and Kword already have partial support for docbook. If there were more, then we could see some real changes on searching the web. Coding for SGML is more difficult, so the obvious choice would be to start from Docbook XML.
