> As an example, I have been looking at CouchDB,
which uses JSON.
> Brief summary of CouchDB:
>
>   1. A B-tree manager whose records are
JSON expressions.
>
>   2. Open-source, available from Apache,
with bindings to all common
>    programming languages, including
_javascript_ and PHP.
>   ÂÂÂ
http://couchdb.apache.org
>
>   3. An HTTP interface for queries and
updates, which uses map-reduce
>    to take advantage of as many
CPUs as your server may have.
>
>   4. Documented by an O'Reilly book with
a draft available for free:
>   ÂÂÂ
http://guide.couchdb.org/draft/index.html
>
> At the end of this note is a sample JSON
_expression_ used by CouchDB.
> Any quoted string could be a URI or it could be
raw data of any length.

library, and your boss

to Linked Open Data

>   2. Download and install CouchDB.
>
>   3. Write a trivial program to map each
record in the library catalog

similar to the example below.

record from the library

store it in CouchDB.

>   5. Write a web page that tells any web
master anywhere in the world

for accessing that DB.

 One JSON structure

than multiple RDF triples.
