To create a REST-based application using MarkLogic, you first need three things:
- a database,
- a RESTful server (called a "REST API instance"), and
- some users with the appropriate privileges.
You'll create each of these in this section.
This tutorial assumes the following configuration. You can use different values than these; you'll just have to modify each example accordingly:
Download and install the latest version of MarkLogic from this page: http://developer.marklogic.com/products. Once you've installed and started up MarkLogic, go to the browser-based administrative interface (at http://localhost:8001/), where you'll be walked through the process of getting an Express license, as well as setting up an admin user. (This tutorial assumes you'll be running MarkLogic on your local machine; if that's not the case, just substitute your server name whenever you see "localhost" in this tutorial.)
If you need more detailed instructions on installing and running MarkLogic, see Installing MarkLogic Server.
Navigate in your browser to http://localhost:8000/appservices/ and click the "New Database" button near the top of the screen:
In the dialog that pops up, type the new database name "TutorialDB" and click "Create Database":
You've now created the "TutorialDB" database with the default configuration.
Enable the collection lexicon
The collection lexicon is an indexing feature that we'll need for the tutorial. Back at the top of the window, make sure "TutorialDB" is selected and click the "Configure" button:
Then click the checkbox next to "Collection Lexicon":
Now you'll create the REST API instance for interacting with the database. On the same page, under "REST API Instances," click the "Add New" button:
Type "TutorialServer" as the server name and choose a port number. In this tutorial, we'll use port 8011:
You should now see "TutorialServer" in the list:
By creating a REST API instance in this way, MarkLogic has automatically created and configured the underlying components for you (specifically, an HTTP app server and an associated modules database). To prove that the REST API instance is running, navigate in your browser to http://localhost:8011/. You should see a page that looks something like this:
Try clicking some of the links to see the output returned. This is just a preview of what's to come.
The rest of this tutorial assumes that you'll be running MarkLogic on your local machine at port 8011. If that's not the case, you'll need to accordingly modify the host and/or port of each example.
MarkLogic has a powerful and flexible security system. Before you can run the tutorial examples, you'll first need to create a user with the appropriate execute privileges. You of course could use the "admin" user (which has no security restrictions), but as a best practice, we're going to create two users:
- one with the "rest-writer" role, and
- one with the "rest-admin" role.
(There is also a "rest-reader" role available, which provides read-only access to the REST API, but we won't be using that.)
Back in your web browser, navigate to "Security"->"Users" in the admin UI at http://localhost:8001/:
At the top of the User Summary screen, click the "Create" tab:
On the New User screen, enter the username ("rest-writer"), password ("x"), and optional description:
Then scroll down and check the checkbox next to the "rest-writer" role:
Click the "ok" button at the bottom of the page to create the new user.
Repeat the same process (start by clicking the "Create" tab again) for the "rest-admin" user (also with password "x"). Only this time, check the "rest-admin" role instead:
If you click the "Summary" tab, you should now see both users, with their associated roles (including inherited roles).
Now we've got everything set up on the server side, so let's start interacting with MarkLogic via the REST API.
