Sentient Data Access
CowboyRobot writes "From Queue comes a piece subtitled Why doesn't your data know more about you? From the article: 'It has been more than ten years since such information appliances as ATMs and grocery store UPC checkout counters were introduced. ... A common language for these devices has not been standardized, nor have current database solutions sufficiently captured the complexities involved in correctly expressing multifaceted data. ... As computing devices expand from the status-quo keyboard and desktop to a variety of form factors and scales, we can imagine workplaces configured to have a society of devices, each designed for a very specific task. As a whole, the collection of devices may act much like a workshop in the physical world, where the data moves among the specialized digital stations. For our society of devices to operate seamlessly, a mechanism will be required to (a) transport data between devices and (b) have it appear at each workstation, or tool, in the appropriate representation.'"
I guess starting out a scientific paper with "Hey, wouldn't it be cool if..", but their paper really needs it.
One line blog. I hear that they're called Twitters now.
i'm not an expert on the subject.... but, at least in the case of devices like ATMs, which have fairly simple tasks, how would we benefit from a standardized language? i put my PIN in, money comes out, my bank account balance goes down. the elegance of the code behind it doesn't concern me.
i know that "security through obscurity" is a cheesy solution, but i can't help thinking that if every ATM in the country had the same architecture, the system as a whole would be more prone to hacks and abuse. what do you think?
From Queue comes a piece ...that shows clearly just how little the author knows about computing.
The entire point of computers is that they are general purpose devices. The "workshop" idea surely sounds cool to someone who doesn't know about computers, because it resembles the world before "general purpose" was a graspable concept.
Would I rather want my workplace to be a collection of specialized devices, or a single device that can be configured to be any of the others, plus whatever else or new is necessary? Now that's a difficult question, right?
Assorted stuff I do sometimes: Lemuria.org
XML only solves the first problems of data merging, like making the formats easy to parse correctly and using the right international character set.
RDF/XML solves a bit more of the problem, making the structure of the information clear, in terms of assertional statements. An RDF/XML file is a knowledge base, full of statements saying this has some particular relationship to that. It lets the machines get at more of the information in a uniforn, universal way.
But still, the problem of ontology/schema/vocabulary mapping remains: if one system is talking about patients and another is talking about clients, they might or might not really be talking about the same thing. A single person maybe never counts as two patients but sometimes counts as two clients, etc. At least with the data in RDF, most of this mapping can be done in software once a person figures it out and expresses it in a suitable logic language.
The emerging design of the Semantic Web hopes to make that reasonable, but also to support convergence on common vocabularies by having everything on the web -- if it's trivial to see what vocabularies are already being used, people will mostly only make new ones when the old ones really are different.
Other hard problems remain, of course, like figuring out which data sources to trust. Fun fun.
Did anybody try to read the article ? Holy, that is the type of logic that drove me away from social sciences. And the authors seem to be computer science guys !
Let's see what this is all about:
1) FIND AN OBVIOUS TREND
We think microprocessors are spreading everywhere, and see/predict they doing a lot of things, including communication
2) GIVE IT A SOPHISTICATED SOUNDING NAME
I think I will call it... UbiComp (ubiquitous computing)!.
3) ELABORATE ON WHAT NAMED TREND WILL IMPLY
Computers will be everywhere. People will talk to them. They will talk to people... they will talk with each other ! (claps)
4) WRITE ABOUT WHY IMPLICATIONS DIDN'T HAPPEN
"New forms of interaction must be developed for this environment (...)"
5) PEPPER IT ALL WITH UNBEARABLY OBSCURE PHRASES
"Thoughts exchanged by one another are not the same in one room as in another. This includes "thoughts" exchanged between people and/or machines, and implies that behavior is sensitive to location, and as a consequence of mobility, must adapt to changes in physical and social location." Make sure you make references to lots of other authors and experts.
6) RELEASE TEXT TO A "WANT TO LOOK INTELLECTUAL" AUDIENCE
Which will pretend this is the smartest piece of writing ever, and the uninitiated simply are just not smart enough to understand.
No thanks, I think I can do without concepts like UbiComp.

Unfortunately, this kind of thing still starts in the military world. The DoD has been developing requirements for Network Centric Warfare (NCW). Basically turning warfare interfaces into a RTS game like StarCraft, C&C, complete with fog-of-war, semi-autonomous units, comm & data sharing, etc. On the technical side, this is manifesting itself as Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance (C4ISR) architecture. One of the first actual implementations is being worked in in the form of Future Combat Systems (FCS).
These are complex systems, so the DoD has been maturing development of modeling & simulation interoperability by making contractors adhere to High Level Architecture (HLA) so they can properly analyze these systems before deploying them. HLA basically provides a lot of the same data object registration, distribution, and interfaces that older tech like CORBA does, with extra simulation concepts.
These technologies are being commercialized under the buzzwords "Nework Centric Operations" (NCO) and "Network Enabled Operations" (NEO). Advocates usually point to well networked operations like Wal-mart, UPS, et al. as poster children for what could be done (automatic restocking, package tracking, load balancing & route optimization, etc.) with enough NEO infrastructure. A lot of the interchange standards (including C4ISR) are getting established through bodies like the OMG. Other than the interchange standards, there's not all that much new tech involved... maybe RFIDs and various other networking tech (grid/mesh networks, strong encryption/authentication, mobile IP, etc.). Most if it just involves looking at technology that already exists and figuring out how to piece it together to actually do something worthwhile.
Disclaimer: I work for one of the gov't contractors throwing all these buzzwords around.
