David Chalmers and David Bourget are creating a taxonomy of philosophy. David C blogs about it here.The notion of conceiving of philosophy as a tree, with each topic in one right spot, strikes me as both a producing of meaning and a paring down of meaning. But, if it’s useful in some contexts, then great. [LATER: This link back to this post is really informative and interesting.]

Academia.edu lets you add yourself to its gigantic Tree of University Departments. It’s a slick, slidey, Ajaxy UI, and there seem to be only benefits to adding your name to it, even though it will forever be incomplete.

The question is whether it’s easier and more beneficial to count on participants to centralize their contact info at Academia.edu or to hope that universities somehow might agree on a metadata standard — a microformat — for how they list faculty members on their own sites. Since the latter isn’t happening, the former becomes appealing. (Thanks to John Palfrey for the link.)

Kevin Kelly has a terrific piece about edge-notched cards. They’re interesting to me because I’ve been working on a piece that’s part of a piece, that may be part of some other piece that uses the history of the punch card as a way to trace the emergence of modern information. Edge-notched cards have an interesting place because the notches both indicate data and are used as a physical mechanism for sorting.

Kevin’s post was prompted by Alex Wright’s terrific article recalling Paul Otlet as a network pioneer.

I’ve lived in Boston since 1986, but have never made it into the great Boston Public Library. Until today. My streak was totally broken because the little group digitizing the BPL’s holdings invited me in to see what they’re doing. And, oy, the work they have cut out for them!

But they’re an intrepid band. And they recognize that they’re up to something important. Although some in the BPL may have thought that digitized prints and photos are just lesser-qualities backups, the group knows that they’re not only bringing hidden images into the public sun, they are engaged in a social project that changes how and what we know. (What’s not to love about librarians?)

The Print Stack, where photos, prints and miscellaneous other objects are stored, only seems to be in the basement. The ceiling is low, there are no windows, and the lighting leaches vitamin D out of your body. It’s long and overflowing, reminiscent of the warehouse that ends Citizen Kane, and that is echoed in two Indiana Jones movies.

If you want to find a particular image in the roughly two million prints and images (no one knows for sure), you ask Aaron. Some bits and portions have catalogs of various sorts, but overall, it’s a disarray of metadata. For example, the Herald Traveler collection of photos has about 1.2 million pieces, arranged in 104 cabinets, each with four drawers. The folders and drawers are labeled, which helps a lot, but they’re not indexed, much less cross-indexed.

Herald Traveler collection

At least those photos have captions. Aaron shows me some beautiful 19th century photographs of Indian architecture. Many years ago, the BPL went to enormous trouble to paste the photos into multiple volumes — turning the photos into a book, as Aaron points out — but didn’t bother to record the notes on the back of the photos. Aaron is now going to have to dissolve the pages to expose the notes.

Aaron holds up a degraded negative.
A dirigible is barely visible on it.
Tough reclamation project.

The archive doesn’t just have pictures and prints. It’s got, well, everything, including a couple of old typewriters and a collection of matchbook covers from Boston restaurants.

Boston matchbook cover collection

Of this abundance, the digital group has so far scanned about 24,000 objects. When I point out to Maura Marx, the group’s head, that, given the library’s estimate that it has maybe 23 million objects, she’s looking at a 2,000 year project, she tells me that they’re just getting started. They’re going to bulk up, maybe do some offsite digitizing, and begin to make some serious progress. When I ask Thomas Blake, who does the actual digitizing, how he decides which stuff to do, he laughs a little and says, “What I think is cool.” And, since the public has an appetite for “choochoo trains, maps and postcards,” he’s done a bunch of them. The BPL is, after all, a public institution that both serves the public and relies upon the public’s support.

The Library has been posting digitized works at Flickr. Take a look at the 19th century photos of Egypt, or, yes, the postcards And the book fetishists among you should definitely check out the “Art of the Book” collection. Predictably and hearteningly, the public — you and me, sister — have been commenting and adding to what’s known. Maura hopes to get permission to put the images into the Commons. Digitizing and posting — “scan and release,” in the group’s memorable way of putting its mission — turns patrons into historians.

The scanning is slow because it’s one guy who’s doing a careful job. The camera has a 22 megapixel chip, but they’ve been known to digitize at 88mps, creating files that are half a gig in size. Tom likes saving the RAW files to avoid unnecessary data loss. You never know what’s going to be useful. For example, he had been scanning postcards at 300 dpi, but a curator pointed out that then you couldn’t see the dotscreen pattern, which might be of interest to someone. So now Tom scans them at 600dpi. Overall, they have about 1.5 terabytes of stored images.

The metadata is a whole ‘nother issue. Chrissy Watkins, who has been there for four days — she had been at the JFK Presidential Library — is working on it. For now, Tom gives every item an arbitrary and unique ID number, the key piece of any metadata scheme. But the BPL is facing the inevitable conundrum: Maximize the metadata but slow the process, or gather less metadata but go at a far faster clip. The group seems to be leaning toward the latter, which makes sense to me. They’ve been using what Tom calls the “Curator Core,” a reference to the Dublin Core metadata standard for books. Trying to capture everything that might be useful is a task beyond daunting. For example, Michael Klein points to “fore-edge paintings,” paintings done on the edges of a book that are revealed when you fan the book slightly. Does the BPL have to come up with a standard that includes whether you fan the book to the left or right? There are so many different types of objects that building a standard or an ontology that captures them all would absorb all of the team’s time. (“The special case is not as special as you’d think,” says Michael.) Instead, they need to scan scan scan, and capture some reasonable set of metadata, to which more metadata can accrete.

One of the ten Open Content Alliance book scanners.

“We’re going from collect and hide to scan and release,” says Tom. And in so doing, the until-now unpublished holdings are going not just from no value to some value. The digital group is in fact radically multiplying the value of the Boston Public Library’s holdings. And as we the recipients of this gift incorporate the images, adding information to them, and contextualizing them, we are further enriching the holdings, far beyond what any small group, no matter how intrepid, could manage.

Sam Oh teaches at Sungkyunkwan U in Korea and heads the ISO committee responsible for Topic Maps (among other things). (I had the pleasure and honor of having dinner with him last night.) [Caution: Live-Blogging]

FRBR tries to capture the various levels of abstraction of our works. Group 1 consists of: work, expression, manifestation, and item. “A work is realized through an expression” that is “embodied in” a manifestation and “is exemplified by an item.” E.g., Othello is a work which may be expressed in English or in Korean. A particular edition of a book is a manifestation, while a particular copy is an item.

Group 2 consists of people and corporate bodies responsible for creating Group 1.

Group 3 are the subject entities that “serve as the subjects of intellectual or artistic endeavor” Concept (topical subject heading), object (name for an object), even (name for an event), place (name for a place). Sam says that FRBR adopted these from topic maps.

There are some defined relationships among these three grups: A work is by a person, a manifestation may be produced by a corporate bdy, etc. Ad there are work to work relationships such as successor, supplement, complement, translation, etc.

Currently, everything is focused on the manifestation level. That’s at the center of the map, so to speak. A future direction for library systems: Applying FRBR in services to present search results, to streamline cataloging, and to express new insights into works. FRBR can “naturally” be rendered in topic maps, he says.

Sam talks about mapping MARC (standard bibliographic records) to FRBR. The OCLC has an algorithm for converting these.

He shows some examples of pages and maps. He also notes that FRBR’s terms for talking about these levels of expression aren’t clear to a general public. E.g., most people don’t talk about “manifestations.” He’d like to see better terms, especially as FRBR gets exposed more widely. He also thinks the library community should come to know topic maps better.

Petter Thorsrud is a senior advisor to the Norwegian government and responsible for the government’s Web site. He’s going to talk about the “State of the Nation” with regard to semantic interoperability. There was a forum last fall with many governmental groups participating, including education, municipal services, parliament, tax services, etc. Things are moving along.

Marit Lofnes Mellingen [maybe — that’s who’s listed in the program, but they didn’t introduce her by name] gives some examples of semantic interoperability. Semantics is about agreeing on names, she says. The agreement should be minimal so you don’t have to agree on the entire universe.

She points to examples in the health sector. In one case, there are 400 subjects organized into two levels of categories, with synonyms, as well as document type, date, organizational relation (= facet). It uses Dublin Core for documents. “MyPage” is a personalized info portal for citizens. It uses the LOS ontology.

Challenges: Extending the adoption of the common ontologies, merging them with others, driving the categories down to the right level of granularity (so users don’t get too much info). To do this, she thinks we should identify “semantic glue” on a lower level. Also, she’d like to see the ontologies published and made free to use, to enable mashups.

Robert Keil (ex of Razor Fish) says behavior is shifting: People now enter pages through searches, not only through the home page. And the number of portals is increasing. Users want info from the government, but there are many portals to the government.

He shows the Parliament portal” Stortinget.no. It tries to create semantic interoperability around topics. They try to make sure all the retrieved documents are relevant to the query. They use topic maps for this. The status of a matter is presented graphically, with the relevant documents arranged via the info in a topic map. They want to be able to show every parliamentary question with all the relevant info.

Altinn is an Internet portal for “public reporting.” You can get your forms and services there for 20 Norwegian government agencies. The information portal is based on topic maps. It’s smart about the dependency of forms on one another.

Status: Robert quotes Petter: “Before sustems can exchange data, the people behind the systems need to echange information.” Robert says there’s a lot of enthusiasm in the government for semanticizing its information. “We are past the tipping point.” [Tags: topic_maps semantic_web norway ontologies everything_is_miscellaneous ]

Lars Helgeland says that Ted Nelson called Web sites “decorated directories.” The Web has failed the expectations of the Web’s visionaries, Lars says. Topic Maps can help.[Caution: Live-blogging]

Web sites have become reflections of their technical structure, which is usually hierarchical. Knowledge is not natively hierarchical. Knowledge works through people associating ideas.

Lars shows examples of sites redesigned using topic maps; they use the knowledge representation of topics maps without using the familiar circles-and-lines display. “We need to see portals as layered architecture, where content is independent of both presentation and the underlying technology structures.”

Alex Wright is keynoting the Topic Maps conference in Oslo. [I’m live blogging, getting things wrong, etc.]

Europe has been thinking about organizing information for a long, long time, he says. He goes basck to Thomas Aquinas who thought the two pillars of memory: Association and order. He likens “memory palaces” to topic maps. [Hmm. The associations weren’t topical, as I understand them.] He fast-forwards to Charles Cutter who invented a book cataloging system and foresaw in 1883 the day when clicking on a reference would retrieve the object. [Cutter numbers are routinely added to Dewey Decimal numbers in library catalogs.] H.G. Wells in 1938 foresaw an infrastructure for sharing info electronically. Teilhard de Chardin wrote about the “noosphere.” [It’s been a long time since I read him, but I recall the noosphere as a spiritual realm, not a tech realm. I could be entirely wrong.]

Alex points especialy to Paul Otlet, a Belgian who thought libraries were too fixed on books. Rather, we should be thinking about the structure of information within and across books. There’d be an underlying classification scheme, represented in index cards, pointing to books. He tried to actually build this, starting in 1921. He invented the “Uniersal Decimal Classification” scheme. The UDC was designed to classify the info inside of book. Auxiliary Tables marked relationships between topics, i.e., typed links. [The Web only succeeded because it let the typing of links be accomplished by the words around it.] He also had the idea of a social space around information.

Alex visited the Mundaneum — an Otlet museum — a few days ago and shows photos. Very cool. They’ve only managed to catalog a tenth of the collection in the past ten years.[Pretty good argument against Otlet’s idea. It doesn’t scale.] He shows pictographic representatives showing how info can be remixed and browsed.

Alex points to facetag, an Italian project that uses faceted classification that are established at the toplevel. Within that, users assign their own tags. Also vote-links puts meaning into hyperlinks.

Next Alex turns to Vannevar Bush and “How We May Think,” the essay that proposed the memex. In some ways, it was more sophisticated than the Web, he says. E.g., whe you made a link, it was visible in both directions. And the trails should be public so there could be collective intelligence.

Eugene Garfield was inspired by Bush and founded the Science Citation Index, which ranked citations. Doug Engelbart was also inspired by Bush. (He recommends Englebart’s “mother of all demos” demo, which is indeed truly amazing.) Engelbart was concerned with tools for group colaboration, process hierarchies, and multi-level nesting of organizational knowledge. He points quickly also to Xero PARC’s “note cards,” Apple’s Hypercards, Ted Nelson, Andries van Dam, and others. When the Web became dominant, Alex says, a lot of promising prior research dried up, which is a shame.

Thje Web that wasn’t” Tying top-down taxomonies with bottom up social space; two say linking; visible pathways; typed associations…

[Terrific talk. Great to hear some history. [Tags: alex_wright internet_history topicmaps ]
