Dicoogle IPFS Storage Plugin

This is a Dicoogle plugin to support the storage of files over IPFS.

Getting Started

IPFS is a P2P distributed file system that targets to connect all computing devices with the same system of files. IPFS provides a high-throughput, content-addressed block storage model, with addressed with a hash URI. Dicoogle IPFS is as far as we know, the first PACS archive supporting DICOM communications with IPFS capabilities.

Run IPFS Daemon

1. First, go to and download the IPFS. You can use Go IPFS Daemon.

2. Run init to create the hash files and keys with:

   $ ./ipfs init

3. Start the daemon:

   $ ./ipfs daemon

It should retrieve something similar:

Daemon is ready

Using your plugin

1. Copy your plugin's package with dependencies (target/ipfs-plugin-1.0.0-SNAPSHOT-jar-with-dependencies.jar) to the "Plugins" folder inside the root folder of Dicoogle.

2. Run Dicoogle. The plugin will be automatically included.

Configuration

You can configure the IPFS endpoint in the Plugin settings. Check here:

| => cat Plugins/settings/IPFS.xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<configuration>
    <ipfs>
        <endpoint>/ip4/127.0.0.1/tcp/5001</endpoint>
    </ipfs>
</configuration>

Available services

If Dicoogle is running on PORT 8082:

Check the current status

Status Web service available at: ipfs/status?action=status

URL: http://localhost:8082/ipfs/status?action=status 

Check the number of local files on IPFS

List Web service available at: ipfs/status?action=fileCount

URL: http://localhost:8082/ipfs/list?action=fileCount

List of local files hashes on IPFS

List Web service available at: ipfs/status?action=fileList

URL: http://localhost:8082/ipfs/list?action=fileList

Test data

This repository uses DICOM data for testing. The DICOM files listed under src/test/resources are made available by NEMA in ftp://medical.nema.org/medical/dicom/DataSets/WG02/RDSR/.

Troubleshooting

By default Dicoogle and IPFS Daemon open the 8080 tcp port, so one of application should change the port to avoid problems.

Use case

1. Store medical imaging over IPFS
2. Failures
3. Avoid changes in medical imaging
4. Allow tracebility
