To store an item in APTrust, simply bag it in valid APTrust format and upload it to your institution's APTrust receiving bucket. Your receiving bucket for the demo system is: For the production system, it's: Replace <institution.domain> with your organization's domain name. For example, virginia.edu, jhu.edu, etc. You'll need AWS keys to complete the upload. If you don't yet have them, contact support@aptrust.org. You can upload bags with Amazon's S3 CLI tools, or by integrating one of Amazon's S3 client libraries into your own tools, or by using APTrust's partner tools. Monitoring the Ingest Process APTrust periodically scans the receiving buckets and adds new bags to the ingest queue. You can see the status of all work requests by clicking the Processed Items tab in our Web UI. Click on an item to view status details. You can also programmatically retrieve the status of work items using the Items endpoint of the member API. The ingest process follows these steps:
Once a bag enters the work queue, ingest can take anywhere from one minute to several hours. The two factors that affect ingest time are bag size and system load. When APTrust is flooded with ingest requests, several hours may elapse between your bag appearing in the work queue and Step 1 of the ingest process. Bags containing large amounts of data always take a long time to process, because we have to retrieve the bag from the receiving bucket and calculate md5 and sha256 checksums on all of the bag's contents. |
