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>
