Retriever

This repository contains the source code of the Retriever module developed within the WP3 of the SALTED Project. The aim of this module is the forwarding of requests to the Context Broker and provision of different format representations, as part of the CKAN connector. To this end, this component enables two URL resources for each type of request allowed (see Usage).

Usage

As mentioned previously, this Retriever module does the forwarding of requests, acting then as a proxy. The two URL resources accessible for this module are:

  • /retriever/realtime/__<entity_type>__.<representation_format>

    This resource allows the query of realtime data (i.e. last records) for a specific data type in a specific format. Example:

    GET /retriever/realtime/__https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus__.json

    This request will perform the next query to the Context Broker:

    GET /entities?type=https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus
Accept: application/json

  • /temporal/__<entity_type>__.<representation_format>?<temporal_unit>=<value>}, with temporal_unit = ["year", "months", "weeks", "days", "hours"]

    This resource allows the query of temporal data (i.e. temporal records) for a specific data type in a specific format. Example:

    GET /retriever/temporal/__https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus__.jsonld?days=5

    This request will perform the next query to the Context Broker:

    GET /temporal/entities?type=https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus&timerel=after&timeAt=<date>
Accept: application/ld+json
# with <date> = datetime.now()-5 days

Installation

Once you have the repository code in your machine, follow the next steps:

  1. Create a .env file and add your information (parameters to change: EXTERNAL_PORT, INTERNAL_PORT, HOST_NAME).

    cp .env.template .env

  2. Create a config.json file and set up the variables to your needs.

    cp config.json.template config.json

  3. Deploy the docker

    docker-compose -f docker-compose.yml build
docker-compose -f docker-compose.yml up
# or do it together
docker-compose -f docker-compose.yml up --build

Retriever
This repository contains the source code of the Retriever module developed within the WP3 of the SALTED Project. The aim of this module is the forwarding of requests to the Context Broker and provision of different format representations, as part of the CKAN connector. To this end, this component enables two URL resources for each type of request allowed (see Usage).
Usage
As mentioned previously, this Retriever module does the forwarding of requests, acting then as a proxy. The two URL resources accessible for this module are:
  • /retriever/realtime/__<entity_type>__.<representation_format>
    This resource allows the query of realtime data (i.e. last records) for a specific data type in a specific format.
Example:
    GET /retriever/realtime/__https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus__.json

    This request will perform the next query to the Context Broker:
    GET /entities?type=https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus
Accept: application/json

  • /temporal/__<entity_type>__.<representation_format>?<temporal_unit>=<value>}, with temporal_unit = ["year", "months", "weeks", "days", "hours"]
    This resource allows the query of temporal data (i.e. temporal records) for a specific data type in a specific format.
Example:
    GET /retriever/temporal/__https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus__.jsonld?days=5

    This request will perform the next query to the Context Broker:
    GET /temporal/entities?type=https%3A%2F%2Fsmartdatamodels.org%2FdataModel.Battery%2FBatteryStatus&timerel=after&timeAt=<date>
Accept: application/ld+json
# with <date> = datetime.now()-5 days

Installation
Once you have the repository code in your machine, follow the next steps:
  1. Create a .env file and add your information (parameters to change: EXTERNAL_PORT, INTERNAL_PORT, HOST_NAME).
    cp .env.template .env
  2. Create a config.json file and set up the variables to your needs.
    cp config.json.template config.json
  3. Deploy the docker
    docker-compose -f docker-compose.yml build
docker-compose -f docker-compose.yml up
# or do it together
docker-compose -f docker-compose.yml up --build
