I need help with addition of features to Dsapce software. It is an open-source digital repository. (Angular + Java + Rest + Postgres DB)
For an item submission -> First create a community -> create a collection inside community -> An item can be submitted inside collection
Mile stones:
1. Form creation for csv or xlsx file upload. Take all required details for parsing the file in backend. Also, If first row does not contain headers then ask the user to provide the headers for all columns manually through form. (Forms Generation – Forms are generated using ng-dynamic-forms and form content is coming from backend through rest API. They utilized object-oriented programming to create models for each tag type of forms.)
Required fields to be inserted in Form Component: This new form to be inserted in item submission page.
2. Parsing the CSV or XLSX files in the backend and pass the tabular data back to Front end for pagination view.
3. Push the completed tabular data into database.
4. Create one more form (manipulation Form) for the user to input required columnar restrictions and manipulations for different users based on security level.
5. Push the manipulations form data into database. (Somehow we need to specify that these restrictions apply for this specific tabular data).
6. View generations for different users with the applicable columnar restrictions and manipulations.
7. Documentation.

BACKEND INSTALLATION COMPLETE
Frontend Installation:
- Node.js (v14.x or v16.x) – Download the latest LTS version installer and follow the default instructions to install node.js.
Link: https://nodejs.org/en/
- Yarn (v1.x) – Yarn can be installed using npm install. Open command prompt and run the command “npm install -–global yarn”.
- PM2 (or another Process Manager for Node.js apps) (optional, but recommended for Production) – PM2 can be installed using npm install. Open command prompt and run the command “npm install -–global pm2”.
- Download Code (to [dspace-angular]) – Download the latest dspace angular UI from https://github.com/DSpace/dspace-angular/releases
- Install Dependencies – change directory to our dspace angular repository using command “cd [dspace-angular]”, the install the local dependencies by running the command “yarn install”.
- Build/Compile – Go to the path “C:\dspace-angular-dspace-7.3\config” and create a copy of file config.example.yml file and name it as config.prod.yml and do the necessary modifications in the rest section as below.
# The REST API server settings
# NOTE: these must be ‘synced’ with the ‘dspace.server.url’ setting in your backend’s local.cfg.
rest:
ssl: false
host: localhost
port: 8080
# NOTE: Space is capitalized because ‘namespace’ is a reserved string in TypeScript
nameSpace: /server
- Build/Compile – Build the User Interface for Production. This builds source code (under [dspace-angular]/src/) to create a compiled version of the User Interface in the [dspace-angular]/dist folder. This /dist folder is what we will deploy & run to start the UI.
Go to path “C:\dspace-angular-dspace-7.3” and run the command “yarn build:prod”.
