How can the origin of my assets be clearly marked, especially if my organization is part of a consortium using Sajara?

Sajara can automatically apply a watermark on each image as it is uploaded to the database. Different collections can be assigned different watermarks.

Who can do what in my Sajara-powered system? How can I limit access to certain parts of the system to certain users?

Sajara currently supports five roles that provide different access to the system. 

1. Anonymous – Any user, whether they register or not, can search the database.
2. Public – Default role for registered users.  Cannot edit metadata but can save favorites, share images, purchase prints and search.
3. Contributor - Able to add and update assets in a particular Collection.
4. Editor – All permissions for a particular Collection.
5. Administrator – All site permissions.
6. E-Commerce Manager – Manage purchase order process.
    

How is the security model implemented and managed for protecting images or categories of images?

Sajara implements image security in several ways:

• Application Roles - A series of roles provides various levels of administrative access to the data.
   
• Off-line Storage - The original images are not stored directly in the Sajara database.  This enables individual units to store collections off-line, if necessary.
   
• Approval Workflow – Sajara can require that assets receive managerial approval before they are visible to the public.
   
• Organization Security –  Each Sajara database can support multiple collections from multiple organizations.  Only users associated with a particular organization are allowed to edit the assets belonging to that organization. 
   
• SSL Encryption – SSL encryption (HTTPS) is activated for all pages related to the purchase process as well as any data exchanged with the credit card fulfillment vendor.

What if all of my assets don’t have an associated geographic location?

The assets and the metadata associated with them can still be stored in the Sajara database and will be able to be searched by keywords, tags, and other non-geographic search criteria.

How does Sajara deal with a collection that has a global geography?

Sajara’s geocoder is extremely powerful and can handle locations in every part of the world. Sajara is capable of using geocoding services made available by ArcIMS, ArcGIS Server, Google Maps, Yahoo, and Microsoft Virtual Earth.

How can I use Sajara to engage my constituents or members of the public?

Sajara has a number of features to encourage public involvement and community assistance in improving the database. 

Visitors to a Sajara website can utilize an optional scan request feature to request additional images or scans of an asset. Each asset can also be equipped with an error report link, enabling visitors to submit correction suggestions or report additional information about an asset. 

Other community-building features in Sajara include the ability to share photos, save favorites, enable public commenting on images, create a user profile, build electronic newsletter lists and implement an optional, integrated blog.

Does Azavea provide digitization services?

No, but we have worked with several organizations to implement digitization efforts and can provide recommendations on digitization processes. We can also refer you to other groups such as the Center for Digital Imaging, Inc with whom we have partnered in the past.
