A quiet revolution in KM?
Many thanks to Justin Kestelyn who recently highlighted Alejandro Vargas' Blog. Alejandro has been quietly putting together a powerful Body of Knowledge on RAC and related issues [still not a "Featured Employee Blog", but it should be!].
I must say, this was a Damascan Road event for me.
During the mid to late 90's, I was heavily involved in Content and Knowledge Management solutions for enterprises. We struggled with concepts of "Human Capital" and "Intellectual Property". In most cases, I was involved in helping companies setup the technical and organisational infrastructure to better empower "knowledge workers" to share, find and reuse information. The solutions of the day were corporate intranets, portals, search engines, mail, groupware and such-like.
I have been somewhat removed from that scene over the past 5 years, and it was only when seeing Alejandro's blog that it really struck me that a quiet revolution has been underway in Corporate Knowledge Management (KM).
The main problems we used to face in knowledge management were cultural, not technical. How to encourage participation? How to reward contribution and reuse? How to effectively organise and locate relevant information? How to measure and align with corporate goals? After years of practice (in both senses of the word), I came to the realisation that the most important contributing factor always came down to having a pivotal community member (not necessarily the formal "leader") around which others would cluster and be inspired to act.
Ironically, the solution to such cultural issues appears to have been technical if I am reading the megatrends correctly.
We saw the first inklings of progress with wikis, which facilitate rapid collective development of a body of knowledge, but now I realise that it is with blogs and podcasts that we are in the process of making a significant step-change.
Now blogs are nothing new. But predominantly we have seen them as a pop cultural phenomenon, creating our first issue of Web Celebs.
Alejandro's blog however epitomises the new breed of not-quite corporate blogging... blogging on a specific topic of interest that relates to their work, but done under personal editorial control. In the past (and still true today), Alejandro's employer would have provided corporate facilities to capture and share the kind of information he is publishing. I'm sure Alejandro still diligently complies with such mandated systems, but it is his blog which is having the most positive impact on the world.
So how is corporate knowledge management evolving with the advent of blogs and podcasts? To my mind, there are two important factors to note:
- Accessibility If a tree falls in a forest and no one is there, does it make a sound? Similarly with knowledge management, what is the value of sharing if no-one uses your work? Corporate knowledge management systems were once able to deliver the optimal audience for your work (if you tried very very hard over a very very long period of time), but the rise of the internet and blogging in particular has changed that dynamic forever.
- Attribution some would say "ego". One critical factor in the success of blogs is that the primary structural organisation is by attribution. It is your collection. Secondary organisation by news aggregators, semantic web or search engines cannot dilute the fact. The days of consigning your masterpiece into the black hole of corporate knowledge are fast receeding. For some, "ego" may be the prime motivation, but I believe it is usually a little more complex than that. Blogs tend to tell a story over time. Posts will be related. As a blog author, you will continually have you history of posts in front of you. Not only does this reinforce the sense of continuing narrative, it illuminates the "gaps" in your story and therefore compels further contribution to fill the void. Just as a novellist may feel compelled to complete their work no matter how unlikely it may be to find a welcoming readership, the blogger is likewise committed to continue what they start. Note that wikis are tapping into a fundamentally different attribution dynamic, one not so much governed by "ego", but by "tribal" aliegance.
"Information is power" is a hackneyed phrase. And I think it doesn't do justice to what is happening in the world today. It is too small town.
I prefer to think in terms of "potential accessibility x attribution = self-perceived value", and "referenced accessibility x attribution = actual value" i.e. power. And I think what we are seeing now is that the tools available (wikis and blogs in particular) are delivering a "value/power" formula that is starting to unleash an unprecedented wave of knowledge sharing and collaboration.
Implicit in the above is a decided shift in "editorial control". No longer is it a neat case of the knowledge worker submitting their work to the whims of the corporate machine. The blogger is in control. That is a significant challenge to the corporation, especially those for which information is the primary product they sell. Alejandro is perhaps fortunate to work a company that makes its money from selling software ... sales that his blogging supports and enhances. But a tax or legal firm? That's a different kettle of fish, since they primarily trade in "knowledge" i.e. expert advice.
So what response should we expect from corporations and developers of "km"/blogging software? Here are a few thoughts...
- We need to see the modern tools (blogs, wikis and podcasts) incorporated as primary sources for corporate KM strategies. That means integration between blogging tools and the corporate KM systems such as customer care/help systems, search engines, semantic webs and intranet/internet portals.
- Locking away such tools as "internal only" resources works against the accessibility imperitive. There are of course valid concerns over confidentiality. To accomodate this dilemma, metadata (and systems) need to support the concept of confidentiality. That is, employees should be able to selectively target internal, customer and public audiences when they post or broadcast. We should be able to adapt approval/moderation processes in accordance with confidentiality.
- In a corporate setting, it doesn't take long before people start questioning the "business value" of all this blogging etc. Personally, I hav ea foot in both camps. On the whole, I believe very few people can justify blogging exclusively on company time. People like Tom Kyte for example [ if we consider Ask Tom a specialised kind of blog]. For most of us however, it's a shared "value capture" equation. Sure, the blogs/wikis etc may enhance our contribution to the business, but a large part can also be a personal development exercise in enhancing our long term career value. In crude terms, maybe that next job will be clinched on the strength of your blog. So just like I read professional books of my choice on personal time, that's when I blog too. As employees, we need to be realistic about this and manage our time accordingly.
- For the corporations themselves, "value capture" can be a trickier proposition. And this depends on the nature of the business too. For a company like Oracle, having employees and users positively blog about its software can arguably give a major (but unmeasurable) sales boost by enhancing "brand value". Maybe we are not quite there yet, but I can imagine a day soon where the lack of an active blogsphere around your software product will make it almost impossible to sell. However to take an extreme example, consider CNN. What if all your reporters actively blogged too? Or if all Ernst & Young's accountants popped up on blogspot? It is harder to implicitly conclude there would be a positive impact on the bottom line. At this point, I see no other solutions than trying to achieve a suitable compromise. The softwares we use play an important role in providing the functionality to achieve that balance faster.
All of the above may be bleeding obvious to some and well discussed in the KM journals, but everyone needs their "Ah-ha" moment, and I just had mine.

Generating CLOB/CDATA elements with XMLDB
Generating CDATA elements with Oracle XMLDB recently got a good airing in the XMLDB forums.
I won't reiterate the discussion there, but offer a summary and some sources.
It seems the current state of affairs is that if you need to generate large text elements with XMLDB you have two options:
- use DBMS_LOB procedural code to manually construct a CDATA element, or
- use XMLTYPE views to construct an XML-encoded element
In both cases you need to be careful not to do anything that casts or converts to varchar to avoid the inherent size limitations.
Note that the XML-encoding in XMLTYPE views is automatic, and I currently don't know how to tell it not to encode but rather quote as CDATA.
Some sources and examples:
- clob-cdata.pl is a Perl script using DBI that demonstrates how to generate an XMLTYPE view over an arbitrary CLOB element, without using XMLSchema. In this case, the CLOB will be automatically XML-encoded [clob-cdata-nonschema.sql is just the plain SQL].
- clob-cdata-schema.sql shows how you can do a similar thing, but using an XMLSchema definition.
- clob-cdata-small.sql shows how you can create CDATA elements where the text size is small using the XMLCdata function

Letting strangers on your Wifi .. need a reason why not?
Sometime back I was hacking my wifi admin pages (to let me register a certain NTP server .. but that's another story), and in the process discovered how broken the security is on my device (an SMC SMC2804WBRP-G Barricade router).
Basically the security check - to make sure you are a valid, logged-in administrator - just redirects to the "action" page which does no further checking of your credentials.
It doesn't take a genius to figure out that if you just post directly to the "action" page you can probably bypass authentication. At least, that's what occured to me, so I tried it and (too my surprise nonetheless) it worked. Or didn't work, depending on your point of view!
To their credit(!), the routine to reset the admin password does require you to send the existing password, but other operations have no barrier.
Here's a simple Perl script that demonstrates how you can "own" an SMC router of this type. It basically lets you reset factory defaults, after which you know the admin password (smcadmin). The factory default has no wifi enabled, so to make any further use of the router you must be connected to a LAN port. But certainly one way to wreck your neighbour's weekend.
I reported this vulnerability to SMC and CERT, but haven't heard whether any action has been taken to fix this.
I also don't know how many other models or brands of routers are susceptible to the same fault. But take this as a warning (and the reason why I am posting this information) ... if you want to offer wifi services to others, make sure your device is not subject to this kind of flaw first!
