			== Generate a business network archive ==

			Now that the business network has been defined, it must be packaged into a deployable business network archive (.bna) file.
			From the tutorial-network directory, run the following command:

			<nowiki>composer archive create -t dir -n .</nowiki>

			== Deploying the business network ==

			<nowiki>composer runtime install --card PeerAdmin@hlfv1 --businessNetworkName tutorial-network
			composer network start --card PeerAdmin@hlfv1 --networkAdmin admin --networkAdminEnrollSecret adminpw --archiveFile tutorial-network@0.0.1.bna --file networkadmin.card
			composer card import --file networkadmin.card
			composer network ping --card admin@tutorial-network</nowiki>

			== Generating a REST server ==

			<nowiki>composer-rest-server</nowiki>

			* <code>admin@tutorial-network</code>
			* <code>never use namespaces</code>
			* <code>No</code>
			* <code>Yes</code>
			* <code>No</code>

Created page with "== Prerequisites == Tools: <nowiki>npm install -g composer-cli npm install -g composer-rest-server npm install -g generator-hyperledger-composer npm install -g yo</nowiki> ..."

New page

== Prerequisites ==

Tools:
<nowiki>npm install -g composer-cli
npm install -g composer-rest-server
npm install -g generator-hyperledger-composer
npm install -g yo</nowiki>

Hyperledger Fabric:
<nowiki>mkdir ~/fabric-tools && cd ~/fabric-tools
curl -O https://raw.githubusercontent.com/hyperledger/composer-tools/master/packages/fabric-dev-servers/fabric-dev-servers.zip
unzip fabric-dev-servers.zip

cd ~/fabric-tools
./downloadFabric.sh</nowiki>

== Generate a business network structure ==

<nowiki>yo hyperledger-composer:businessnetwork</nowiki>

* Enter <code>tutorial-network</code> for the network name, and desired information for description, author name, and author email.
* Select <code>Apache-2.0</code> as the license.
* Select <code>org.acme.biznet</code> as the namespace.

== Defining a business network ==

A business network is made up of assets, participants, transactions, access control rules, and optionally events and queries. In the skeleton business network created in the previous steps, there is a model (<code>.cto</code>) file which will contain the class definitions for all assets, participants, and transactions in the business network. The skeleton business network also contains an access control (<code>permissions.acl</code>) document with basic access control rules, a script (logic.js) file containing transaction processor functions, and a package.json file containing business network metadata.

The first document to update is the model (.cto) file. This file is written using the [https://hyperledger.github.io/composer/latest/reference/cto_language.html Hyperledger Composer Modelling Language]. The model file contains the definitions of each class of asset, transaction, participant, and event. It implicitly extends the Hyperledger Composer System Model described in the modelling language documentation.

Open the org.acme.biznet.cto model file to edit it.

The transaction processor function file contains the JavaScript logic to execute the transactions defined in the model file.

Open the logic.js script file to edit

Adding access control '''(optionnal)'''

* Create a <code>permissions.acl</code> file in the tutorial-network directory.
* Add the following access control rules to <code>permissions.acl</code>:

<nowiki>/**
* Access control rules for tutorial-network
*/
rule Default {
description: "Allow all participants access to all resources"
participant: "ANY"
operation: ALL
resource: "org.acme.biznet.*"
action: ALLOW
}

rule SystemACL {
description: "System ACL to permit all access"
participant: "ANY"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}</nowiki>
