## MTO Ontology Classes

### mto:TransferElement

Gives information about the transfer of a single element - typically a file. The properties in this class would need to be changed if it has to handle sync elements as well

`Superclasses` :

  nie:InformationElement,

`Subclasses` :

  --

`In domain of` :

  mto:state, mto:completedTime, mto:startedTime, mto:destination, mto:source,

`In range of` :

  mto:transferList,

#### Note:

This class notifies about changes

### mto:UploadTransfer

Handles transfers of files/data present on the device to some place outside the device. Upload methods include uploading to a website, sending via BlueTooth etc.

`Superclasses` :

  mto:Transfer,

`Subclasses` :

  --

`In domain of` :

  mto:transferCategory,

`In range of` :

  --

### mto:TransferMethod

Class with a restricted set of instances to enumarate transfer methods

`Superclasses` :

  --

`Subclasses` :

  --

`In domain of` :

  --

`In range of` :

  mto:method,

`Predefined instances` :

  mto:transfer-method-web, mto:transfer-method-bluetooth,

### mto:DownloadTransfer

Handles transfers of files outside the device into the device. This class will only refer to files downloaded from a website or recieved using BlueTooth etc. Files recieved with messages are not considered here. Those would be handled seperately using nmo:Message

`Superclasses` :

  mto:Transfer,

`Subclasses` :

### mto:SyncTransfer

Handles synchronization between the device and some server (a computer, or a website)

`Superclasses` :

  mto:Transfer,

`Subclasses` :

  --

`In domain of` :

  --

`In range of` :

  --

### mto:Transfer

Represent a single transfer task, which could have multiple transfer elements

`Superclasses` :

  nie:InformationElement,

`Subclasses` :

  mto:SyncTransfer, mto:DownloadTransfer, mto:UploadTransfer,

`In domain of` :

  mto:transferPrivacyLevel, mto:agent, mto:starter, mto:account, mto:transferList, mto:created, mto:method, mto:transferState,

`In range of` :

### mto:State

Class with a restricted set of instances to enumarate transfer methods

`Superclasses` :

## MTO Ontology Properties

### mto:destination

The destination of the transfer. If the transfer is an download, it would be the URI for a file on the device. If the transfer is a (web) upload, it will be a URL, which will be filled once the upload is completed.
