Sharing Catalogs and Projects, and Exiting

by Gustaaf Van Moorsel last modified Mar 06, 2017 by Lorant Sjouwerman

When the project, source and resource catalogs for the project are created by NRAO, all co-I's on the proposal in the PST are able to access and modify the project source and resource lists automatically. This is also the case for project PBs, SBs and scans in the OPT tool. If a co-I decides to delegate scheduling by a co-investigator that was not on the original list of proposers in the PST, use the Properties tab of the catalog and/or the Project page to add individuals known to the NRAO user data base (otherwise they have to register first).


Sharing Catalogs

However, if you decided to make your (re)sources in a different catalog you have different options to make them available to your collaborators. The most logical way is to start off creating your (extra) (re)sources in the catalogs provided for the project, or to copy the (re)sources from your personal catalog to the project catalog so the catalog name reminds you which project it was used in. If you want to share your newly created catalog with different people, you can again use the Properties tab to add co-I's.

Another option is to export and import the catalogs through locally saved XML-formatted files. When saved locally you have all freedom to communicate and share with your co-investigators, e.g, that are not in the NRAO data base. You would want to check your catalogs for correctness if you aren't absolutely sure you have already done so before exporting - do not hand-edit the XML files. Exporting unused catalogs and projects, which later can be imported if needed, also keeps the information contained in the OPT web application limited which will speed up the operation over the web. From the top menu strip select FILE - EXPORT or FILE - IMPORT to interact with a dialog window. The default OPT web application file transfer export or import format is XML, but for the SCT the PST format should allow you to read (and write) the same file as you used to submit your source list to the PST. The latter would obviously be very useful for long lists. The upload field or pressing the download button will interact with your local computer environment according to your browser upload and download settings.


Sharing Projects

As mentioned above, simply add an individual to the project if you like to share it. You can also export your project containing your PBs and SBs to a local disk just like you can save the RCT and SCT catalogs (by selecting FILE - EXPORT) and email the XML files. It may be good practice to do so to keep a copy, and to delete obsolete projects (when not observed) and catalogs when the contents in the OPT web application data base gets large. You will appreciate the increase in speed over the network while you know you can always reload these when you need them again. By the way, the exported XML file is not used for submitting your schedule, just for you and your collaborators to communicate or keep safe.



The proper way to exit the OPT web application is to use FILE - EXIT or click on EXIT on the right-hand side of the blue navigation bar. This will bring you back to the my.nrao.edu portal. Also log out of the portal using the upper right hand side logout link.

Exiting can also be achieved, or happen, due to a long period of inactivity. As the server-side database updates every time you make a change in the OPT in your local browser, there is no need to worry about unsaved changes if you are timed out.

Please, do not use the browser back button to navigate to the previous page. This may give you browser errors and might prevent you from working on your project for a few hours.
