HDDS New Data Notification
HDDS offers the following options for notification of new data acquisitions.
1. Standing Request
The ‘Standing Request’ function allows registered users to run searches for new acquisitions, in the background, using the same criteria as the current search. The ‘Submit Standing Request’ button is at the bottom of the search results list panel (Figure 1) and is only visible if you are logged in to HDDS Explorer.

2. RSS Feed
The ‘RSS Feed’ function allows registered users to subscribe to notifications to receive timely updates of data ingests for specific events. Subscribing to the RSS removes the need to manually check the HDDS website for new data.
To receive notification of new data ingests for HDDS events, click ‘RSS’ on the HDDS Explorer Main menu bar (Figure 6).

The ‘RSS Subscription Menu’ provides a list of options for RSS feeds to subscribe to notifications of all data ingests or to ingests for specific events (Figure 7). Select ‘RSS’ for the desired event(s). Users can use the RSS reader of their choice.

The example shown below depicts how to use the RSS feed in Firefox. Other RSS readers provide similar capabilities.
In Firefox, selecting ‘RSS’ displays options for the RSS feed subscription followed by a list of data ingests for the event (Figure 8).

Select ‘Live Bookmark’ as the application then click ‘Subscribe Now’. The bookmark name has been shortened in the “Subscribe with Live Bookmark’ dialog box to allow the event name to appear on the toolbar (Figure 9).
Figure 9 - RSS Feed on Toolbar
Select ‘Subscribe’ to save the RSS feed to the ‘Bookmarks Toolbar’ for easy access.
Click the link on the toolbar at any time to view a list of batch names for recent data ingests for the event (Figure 10). The batch name typically includes the name of the event, agency, platform, and acquisition date.

Select a new ingest from the list to view the data in HDDS Explorer. The link will open directly to the results tab and show the data included in the batch ingest. The feeds icon on the list will change color when the link has been activated (other browsers will remove the link once is has been activated).
The bookmark can be deleted when the RSS feed is no longer needed.
