## General information

The DLT module is used to provide access to the underlying Fabric deployment. It allows clients

to add, retrieve, modify and delete blockchain-backed data, essentially working as a key-value

database. External clients should use REST API to communicate with this service, its detailed

database. External clients should use gRPC API to communicate with this service, its detailed

description available below.



## Code structure
@@ -59,26 +59,17 @@ CRUD interface. 
Other files contain auxiliary code for `FabricConnector` which allows it to register/enroll

users and to obtain smart contract instances.



### HTTP package

Contains server side HTTP handler. It accepts requests from the outside and performs the

requested operation. For the detailed description see API description section.

### Grpc package

Contains server side gRPC handler. It accepts requests from the outside and performs the

requested operation. For the more detailed description see Proto package description right below.



### Proto package

The proto package contains `Config.proto` file which contains messages for REST API. The most

important ones are `DltConfig` (it defines the whole DLT configuration) and `DltRecord` which

represents data to store in the blockchain.

The proto package contains `dlt.proto` file which defines gRPC service `DltService` API and messages

it uses. There are 3 main functions: `RecordToDlt` which allows to create/modify/delete data,

`GetFromDlt` which returns already written data and `SubscribeToDlt` which allows clients subscribe

for future create/modify/delete events with provided filters.

Other proto files don't play any significant role and could be safely ignored by end users.



### Client example

This code is not necessary to the service, but it could be used to test the service. It contains

a sample REST client which connects the service and perform all the CRUD operations. 



## REST API description

| Method | URL | Input | Response code | Output |

| --- | ----------- | --- | --- | --- |

| POST | /dlt/configure | Configuration object | 201 or 400 | Status value | 

| GET | /dlt/configure | - | 200 or 404 | Configuration object |

| POST | /dlt/record | Record object | 200, 201, 400 or 404 | Status value |

| GET | /dlt/record | Record id | 200 or 404 | Record object |



Record and configuration object are defined in `proto` package.

a sample gRPC client which connects the service and perform all the CRUD operations.
