So, now that you've been through the documentation on the API Concepts, XML Format and REST API, let's take a look at a few practical examples of working with the Directed Edge webservices.
For these examples we'll be using the command line tool curl to upload XML to the webservices.

Importing a database
Let's start with a very simple database with three users (with the IDs user1, user2 and user3) and three products (with the IDs product1, product2 and product3).
<?xml version="1.0" encoding="UTF-8"?>
<directededge version="0.1">
<item id="user1">
<tag>user</tag>
<link>product1</link>
<link>product2</link>
</item>
<item id="user2">
<tag>user</tag>
<link>product3</link>
</item>
<item id="user3">
<tag>user</tag>
<link>product2</link>
</item>
<item id="product1">
<tag>product</tag>
</item>
<item id="product2">
<tag>product</tag>
</item>
<item id="product3">
<tag>product</tag>
</item>
</directededge>Curl Command (Download XML):
$ curl -T database.xml https://exampledb:password@webservices.directededge.com/api/v1/exampledb
This imports the structure above into the exampledb database.
Exporting a database
Curl Command:
$ curl https://exampledb:password@webservices.directededge.com/api/v1/exampledb
Produces:
<?xml version="1.0" standalone="yes"?>
<directededge version="0.1">
<item id="user1">
<tag>user</tag>
<link>product1</link>
<link>product2</link>
</item>
<item id="user3">
<tag>user</tag>
<link>product2</link>
</item>
<item id="product1">
<tag>product</tag>
</item>
<item id="product2">
<tag>product</tag>
</item>
<item id="product3">
<tag>product</tag>
</item>
</directededge>Which is what we imported just above.
