The search and browse filters located in the Search Panel of Presentation Mode
use an SOS database that is located on your SOS computer. The database
contains meta-data for NOAA-managed datasets and Site-Custom datasets. Most
sites have automatic updates to their SOS database once per week on Mondays.
However, if you have added a new Site-Custom dataset or NOAA added a new
dataset during the middle of the week that you would like to access immediately
from the database, you must refresh your SOS database.
To do this, simply run the DatasetUpdate Catalog menu
option. This may take a few minutes. Once the update is complete, your SOS
database is now up-to-date and any new datasets should show up in the Search
Results View when filtering. If you have translated Site-Custom datasets, you
need to run the DatasetUpdate Translations menu option
after running the Update Catalog menu option to make
sure your translated datasets get into the SOS database.
From the Menu Bar, click PresentationNew (or you can
click the New Shortcut if in Presentation Mode). Use the Search Panel to narrow
the list of datasets in the Search Results View to find datasets of interest.
Click and drag a dataset from the Search Results View to the Presentation
Playlist View. Datasets can also be added from a reference presentation
playlist in the Reference Presentation View or by navigating to a desired
dataset by clicking the Add Dataset from File button.
Use the Remove Selected Dataset button to remove
datasets from your presentation.
To modify (add, delete, or reorder) the datasets in an existing presentation
playlist, first open the presentation into the Presentation Playlist View by
clicking on PresentationOpen (or you can click the
Open Shortcut if in Presentation mode). Add datasets from the Search Results
View, Reference Presentation View, or Add Dataset from
File button. Use the Remove Selected
Dataset button to remove datasets from your presentation. Click
and drag a dataset to re-order it within the list.
Override or Extend Datasets in a Presentation Playlist
Datasets in a presentation playlist can be overridden or extended so that you
do not have to create a new copy of the dataset, and thus, you can have
alternative versions of the same dataset (i.e. only one folder for the dataset
with its playlist.sos file, with any overrides or extensions only specified in
the presentation playlist file and not in the dataset playlist.sos file).
There are 3 use cases:
Extend the dataset. For example, add your site’s logo to a dataset, or add a
new audio track to a dataset
Override global attributes. For example, change the frames per second to a
Override the files specified for the Audio, Label, or Caption Elements to use
To perform overrides or extensions, double-click on a dataset in the
Presentation Playlist View, which will open the dataset in Dataset Mode. Then,
modify attributes to make an override and/or add Elements to extend the
dataset, as described in the Dataset Mode Tutorial section.
When you are done modifying the dataset, click
Presentation in the Mode Selector to get back to the
Once you are done editing a presentation playlist, click PresentationSave (or you can click the Save Shortcut if in
Presentation Mode). If you want to save the presentation under a different
name, click PresentationSave As and then give the
presentation a name with no spaces or special characters. The .sos file
extension will automatically be added to the end of the file.
Exporting allows you to package everything in your presentation playlist
(including datasets) into a single folder in
/shared/sos/media/site-custom/. Once packaged, the presentation
can be easily shared with other SOS sites and NOAA.
To export, simply click on PresentationExport. A file
browser will appear and you will need to either create a new folder for the
presentation or choose an existing folder. Choosing an existing folder will
delete the contents of that folder before exporting, but you will be prompted
if that folder is not empty. Once saved, a sub-folder for each dataset in the
presentation playlist is created that contains any Elements that have been
modified or added. NOAA-managed data will not be copied, but will be
referenced with an absolute path.
A presentation.sos presentation playlist file is also created in the main
folder that references each of the sub-folders that contain the datasets.
Click PresentationGenerate Summary to create a PDF
file that is a list of every dataset name currently in the Presentation
Playlist View, along with their thumbnails. Presenter Notes, if available, are
appended to the bottom of the list.
