You should check (in Sweden, with Swedish law): https://lagen.nu/ [lagen.nu]

It's the law, combined with cases from Domstolsverket (Courts Administration). He has a tech description to:

I'll try to translate:
he fetches laws from the Cabinet Office web server, which he converts into XML (XHTML2 med RDFa)

He then retrieves cases from the Courts Administration FTP server, also converts this into XML. (via words "save as HTML", and then converting).

He then compiles all the meta-data from all the documents into RDF -graph. This is used in conjunction with style sheets to create XHTML1.0 pages, ready for displaying in a browser.

finally, indexes and Table of contents are created and the result is hosted on Apache-servers. The code is written in python, with parts in XSLT.

Impressive, impressive work. Which landed him a job in e-gov (I hope he keeps the law-project going!)

Well, someone (a hobbyist) is doing just that (in Sweden, with Swedish law): https://lagen.nu/

Technologically, he has a description of what he does. I'll try to translate:

Absolutely.

As mentioned - the space requirement for copying the most outrageous amount of files can be met with a couple of 2TB discs.

And - more intresting, filling the speed requirement:

We will have SuperSpeed USB 3 going mainstream soon (with theoretical transfer speeds of 4.8 Gbps) .
Lets put that in perspective. Depending on that products (HDD's, controllers, external cabinets) appear which could support these transfer speeds,
we could look at speeds where filling a 2TB disc would take 10-15 minutes. Minutes, guys.

That's 15 minutes to grab 75 single layer 27Bg Blue-ray movies, or 400 5GB DVD .ISO's, without any compression.

Prediction: Sneakernet will be hard beaten, in terms of speed, security and capacity.
Only con I'm able to see is availability, where nothing beats the internet.
