 # oc-lib
 
+oc-lib allows read/write/search operations into the main OpenCloud databases.
+
+It also provides common initialization and configuration utilities for all OpenCloud components
+
+## Usage example in a beego API
+
+```go
+const appname = "oc-mycomponent"
+
+func main() {
+    // Init the oc-lib
+    oclib.Init(appname)
+
+    // Load the right config file
+
+    /*  The configuration loader will load the configuration from the following sources:
+    *  - the environment variables with the prefix OCAPPNAME_ - ex: OCMYCOMPONENT_MONGOURL
+    *  - the file /etc/oc/appname.json - ex: /etc/oc/mycomponent.json
+    *  - the file ./appname.json - ex: ./mycomponent.json
+    *  The configuration loader will merge the configuration from the different sources
+    *  The configuration loader will give priority to the environment variables
+    *  The configuration loader will give priority to the local file over the default file
+    */
+    o := oclib.GetConfLoader()
+
+    // init the local config object
+    models.GetConfig().Port = o.GetIntDefault("port", 8080)
+    models.GetConfig().LokiUrl = o.GetStringDefault("lokiurl", "")
+    models.GetConfig().LogLevel = o.GetStringDefault("loglevel", "info")    
+    models.GetConfig().MongoUrl = o.GetStringDefault("mongourl", "mongodb://127.0.0.1:27017")
+    models.GetConfig().MongoDatabase = o.GetStringDefault("mongodatabase", "myDb")
+    models.GetConfig().NatsUrl = o.GetStringDefault("natsurl", "nats://localhost:4222")
+
+    models.GetConfig().mycomponentparam1 = o.GetStringDefault("mycomponentparam1", "mycomponentdefault1")    
+    models.GetConfig().mycomponentparam2 = o.GetStringDefault("mycomponentparam2", "mycomponentdefault2")
+
+    // feed the library with the loaded config, 
+    // this will also initialize a logger available via oclib.GetLogger()
+	oclib.SetConfig(
+        models.GetConfig().MongoUrl
+        models.GetConfig().MongoDatabase 
+        models.GetConfig().NatsUrl
+        models.GetConfig().LokiUrl
+        models.GetConfig().LogLevel
+	)
+
+    // Beego init
+    beego.BConfig.AppName = appname
+    beego.BConfig.Listen.HTTPPort = models.GetConfig().Port
+    beego.BConfig.WebConfig.DirectoryIndex = true
+    beego.BConfig.WebConfig.StaticDir["/swagger"] = "swagger"
+

+}
+```
+
+## SPECIAL FLOWS IN OC-LIB RESUME :
+
+### WORKFLOW AS ITS OWN WORKSPACE
+
+A workflow on post, put, delete, manage a workspace with resources.
+This workspace is deeply related to workflow by sharing its naming such as : "<workflow_name>_worspace"
+
+### WORKFLOW GENERATE ITS OWN EXECUTION
+
+A workflow on post, put, delete, with a schedule && schedule_active to "true", must manage execution by adding, deleting execution 
+depending on change (update -> involved delete into add)
+
+If schedule_active is set to "false" execution will be deleted.
+
+### WORKFLOW GENERATE ITS OWN BOOKING ON PEERS
+
+A workflow on post, put, delete, with a schedule && schedule_active to "true", must manage booking by adding, deleting execution 
+with http requests on peers
+depending on change (update -> involved delete into add)
+
+If schedule_active is set to "false" booking will be deleted.
+
+### SHARED WORKSPACE : WORSPACE & WORKFLOW
+
+You can create a share workspace with workspace & workflow.
+When a share workspace is post, put, delete it update workspace or workflow <shared> field.
+Workspace can be shared on one share workspace 
+Workflow can be shared in multiple workspace 
+
+### SHARED WORKSPACE SHARE TO PEER
+
+When writing a shared workspace, it set up to date on peers involved in shared workspace
+It create or delete shared workspace in remote peers by http requests on oc-shared  (update -> involved delete into add)
+
+It create or delete workspace involved in shared workspace by http requests on oc-workspace  (update -> involved delete into add)
+It create or delete workflow involved in shared workspace by http requests on oc-workflow (update -> involved delete into add)
+
+### WORKFLOW WRITE BUT SHARED
+
+On delete & update & post, workflow will send to peer in <shared> field by http request on oc-workflow
+
+### WORKSPACE WRITE BUT SHARED
+
+On delete & update & post, workspace will send to peer in <shared> field by http request on oc-workspace
