When you open Arbil for the first time the wizard appears and gives you the ability to configure Arbil to your needs. The first window (Figure 2.1) is a welcome window, press Next to move to the second step of the wizard. In this window (Figure 2.2) you select the metadata format i.e. IMDI or CMDI; you can choose one of them or both. In this manual we will assume you will select just CMDI. The third window (Figure 2.3) gives you the ability to choose the corpora and/or the profiles that will appear in the Remote corpus box. If you know the URL[1] of the remote metadata that you will be working on frequently, you can add it to this list so that it will be available on the root level of the tree in the Remote corpus box. After finishing with Remote locations press Next (Figure 2.4) and then Finish. You can reopen the wizard by choosing Run setup wizard in the Help menu.
Arbil can be started in two ways, either via the webstart or by downloading the installer (see here). Note that the webstart does not work for Ubuntu; in this case you will have to download the installer version.
[1] You can copy the URL of a corpus by selecting the node in the remote tree in Arbil when the wizard is not showing, right click and select 'Copy'; or get it from the IMDI browser by navigating to the corpus, right click the node and select 'Create bookmark' and copy the URL link. Then you can paste it into the box in the wizard.
