dp-cantabular-metadata-extractor-api

Supply Cantabular metadata for Florence metadata journey.

Getting started

• Run make debug

Dependencies

• Requires Cantabular Server running on port 8491 (see dp-cantabular-server)
• Requires Cantabular UI running on port 8080 (see dp-cantabular-ui)
• Requires Cantabular Metadata running on port 8493 (see dp-cantabular-metadata-service)

There are also the following further dependencies if running with AUTHORISATION_ENABLED=true (see Running with Authorisation Enabled) :-

• Requires the Permissions API, port forwarded from the relevant AWS environment, running on port 25400

• Requires the Identity API, port forwarded from the relevant AWS environment, running on port 25600

• No further dependencies other than those defined in go.mod

Configuration

Running with Authorisation Enabled

• The following 3 prerequisites need to be run, either directly or in docker:

1. cantabular server
2. cantabular ui
3. cantabular metadata

• Log in to the relevant AWS environment NB. the authentication is done by AWS Cognito in either sandbox, staging, or prod, depending on which environment you log into.
• Use consul to get the IP address and port for both the permissions api and identity api services.
• Port forward to the permissions api like this:

dp ssh <env> <IP address> -p 25400:<IP address>:<port>

E.g. dp ssh sandbox 10.30.139.75 -p 25400:10.30.139.75:22958

• Port forward to the identity api like this:

dp ssh <env> <IP address> -p 25600:<IP address>:<port>

E.g. dp ssh sandbox 10.30.138.21 -p 25600:10.30.138.21:28100

• Make sure that you have a Florence account with admin permissions in the AWS Cognito user pool e.g. the one named sandbox-florence-users. NB. You can find this in the AWS Management Console. If not then ask a Florence admin to create an admin account for you (via Florence).
• Get a JWT token, from the identity api, by sending a POST request to the following endpoint:

http://localhost:25600/v1/tokens

NB. It will require a JSON request body as follows: {"email":"your email","password":"your password"}. The JWT token will be in the response Header and will look something like this (for example):

• export AUTHORISATION_ENABLED=true
• Run the cantabular metatdata exporter api on port 28300

make debug

• Send a GET request to the following endpoint:

http://localhost:28300/cantabular-metadata/dataset/<name of cantabular blob>/lang/<language> 

NB. It will require the JWT Token, including the word 'Bearer', in a Header named Authorization. For example:

curl http://localhost:28300/cantabular-metadata/dataset/RM001/lang/en -H 'Authorization: Bearer eyJraWQiOiJqeFlva3pnVER5UVVNb1VTM0c0ODNoa0VjY3hFSklKdCtHVjAraHVSRUpBPSIsImFsZyI6IlJTMjU2In0.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.MJ7cDY8B7LsdWelCWHw-eLpb-fEBr7NRWwftkj5fbizuIjzdn7shzsV8qetAZtsjRaURjIZwugd3f637zMj0WV76e3Sj3L7QUW-KNQjiKqbYr5RtoeJ91fUv8UaU-o7-74fmhl2Y_D22QQHVngVMKtj74GowA1TA0AoCfR2qml6B5zrgtsizJth1ySPyZHorVkyo-qA4JT_ZJg4x7QbEDJYW43zKD5JASwZcP6KmXl19YfZEvPTf4y7taYiomNU3ro73hKzwuO61wz9KJVqo9JIhSnJ7Lb-Fc86C7BwVYBPHsucxTE5pXaOHY-zKpySe_PV1u6gBnZSPP7-CjuCivQ'
