Use one Site Collection or multiple Site Collections?

Some important concepts:

  • a site collection is a unit of information belonging together; if information should be isolated/secured, it could be a separate site collection;
  • having multiple site collections might require some additional development (e.g. packaging content types or site columns that you want to reuse in different site collections in features);
  • a lot of built-in web parts only work inside a site collection, not across site collections;
  • it’s good to have separate site collections for a corporate, governed intranet and the wild wild west of collaboration 🙂

Microsoft introduces “learning snacks”

To promote their new Windows 2008 server, Microsoft announces the availability of learning snacks. A learning snack is a short module that illustrates one specific topic or learning objective. Of course, Microsoft uses Silverlight as the underlying technology.

Have a look yourself on the Windows 2008 learning portal (click the Learning Snacks tab). Microsoft uses very simple, but effective interactions: mouse-overs, software demonstrations, click-to-reveal-more, …

What I like about it:

  • simple but very nice layout
  • good performance
  • easy to navigate interface

What I do not like about it:

  • voice-over quality is not consistent: sometimes good, sometimes very bad;
  • it does not work on my Mac. There is a Silverlight version for Mac, but the learning snack player does not seem to load the content, not in Safari, not in Firefox;
  • clicking on some of the links is blocked by the IE popup blocker (althoug it seems to be a simple hyperlink)

Still a great initiative. Wouldn’t it be nice if this Silverlight player could load SCORM manifests? What if Microsoft made it freely available? Wouldn’t that be a great promotion for Silverlight?

What people are saying… Definition extraction

Today, I noticed a SharePoint Search feature I did not  know yet: I was looking for the meaning of an abbreviation using the SharePoint Search center, and at the bottom of the first page of my search results a link showed up: What people are saying. After clicking the link, it showed me a perfect definition, and links to the documents were it was found. Cool!

This is what I can find in the Microsoft documentation: the Definition Extraction feature finds definitions for candidate terms and identifies acronyms and their expansions by examining the grammatical structure of sentences that have been indexed (for example, NASA, radar, modem, and so on). It is only available for English.

This means that during the crawling, the MOSS indexer is checking content for sentences like “X is ….”, and recognises them as a definition. It does not seem to be very configurable, but you can turn it off in the settings of the Search Core Results web part. Just uncheck Display Discovered Definition.
