This repo contains AWS SAM templates that deploy a Proof Of Value for a serverless ECM application. This application uses Amazon ML services like Comprehend and Rekognition to index documents and images, and then sends the results to the Amazon DynamoDB Service for indexing.

This application uses an event-based architecture, with Amazon EventBridge as the serverless event bus.

• AWS and AWS SAM CLI configured with Administrator permission
• NodeJS 12.x installed
• You can use GitPod (https://www.gitpod.io/) as you development environment with all this requirements.

1. Clone the repo onto your local development machine using git clone.

2. Then run:

sam build -u
sam deploy --guided --capabilities CAPABILITY_NAMED_IAM

Follow the prompts in the deploy process to set the stack name, AWS Region, unique bucket names, DynamoDB domain endpoint, and other parameters.

Once completed, run

aws s3 sync ACQsite/. s3://myecm-s3-acq

pushd viewsite
myURL=$(aws ssm get-parameter --name ScanAPIUrl  | jq -r '.Parameter.Value')
sed -i "/.get(/c\    .get('${myURL}')" src/FeaturedDocuments.js
npm install
npm run build
popd

aws s3 sync viewsite/build/. s3://myecm-s3-view

to install acquisition and viewer website.

The Acquisition URL will be : https://myecm-s3-acq.s3-eu-west-1.amazonaws.com/index.html

The Acquisition URL will be : https://myecm-s3-view.s3-eu-west-1.amazonaws.com/index.html

You can also use provision and decommission scripts to fully automate the processus.

• Upload PDF, DOCX or JPG, PNG files to the TP or BATCH buckets.
• After a few seconds you will see the index in DynamoDB has been updated with labels and entities for the object and the files moved to the ECS bucket.
