Sharing Rational Engineering Lifecycle Manager Assets with Content Packages
What is a Content Package?
A Content Package is simply a bundle of Rational Engineering Lifecycle Manager (RELM) Assets – for example Views, Queries, Enumerations, Product Groupings, Impact Analysis Profiles and Filters.
Content Packages make it easy to bundle assets to support specific industry processes and practices, for example ISO26262 for the Automotive industry, or DO178B/C for the Aerospace industry. Of course they can also be used simply to share your assets with others. This article shows you how to download and deploy Content Packages as well as how to create your own.
Creating a Content Package
To create a Content Package you’ll need administrative privileges – so make sure you have those before trying.
Creating a Content Package of Views
Open the list of Views and tick the ones you want to include in the Content Package, then click the Export button in the upper right hand corner.
The Content Package is created as a zip file with the naming convention ‘type of content’ followed by an ISO 8601 timestamp.

For example – the Views shown here were exported as a file with the name Views-130920090231.zip

Creating Other Content Packages
Exporting the other types of asset is done in a similar way – but you will need to be using the right version.
- Views – RELM 4.0.3
- Queries, Enumerations and Product Groupings – RELM 4.0.4
- Impact Analysis Profiles and Filters – RELM 4.0.5
Deploying a Content Package
First you’ll need to obtain the Content Pack. You can download the ISO26262 sample Content Pack here: https://jazz.net/wiki/pub/Main/RELMSampleContentPackage/iso26262.zip
RELM also comes with a sample content package – preinstalled as part of the installation.
To deploy a Content Package involves two steps – one on the file system and one using the web interface.
Step One – Making the Content Package Available to the Server
The Content Package is in the form of a zip file – the first thing you’ll need to do is extract the content from it so it’s in a folder. Put that folder on the machine that’s running the RELM server – it needs to be placed in RELM_INSTALL/server/conf/relm/contents.

Step Two – Deploying the Content Package
Using your web browser, log into RELM and navigate into a project. Then, select Deploy Predefined Contents from the Administration menu:

Any folders you added to the server during step one will be available here – along with the sample Content Pack that’s automatically included with the installation. Click Deploy next to the Content Pack you want to install.

Figure 7 – Deployed Content Package
If you deploy the same Content Pack twice RELM will simply have two copies of it – so there’s no danger of accidentally overwriting a View that you’ve deployed previously and modified.
That’s it! If you’ve created some assets you think would be useful for others why not share them with the community?
