Dynamic link

Any link that is not a static link is called a dynamic link. For example, path links do not mount another volume, simply point to another file by an internal path. The link may be broken, as the referenced file may not exist.

File link

A file link is a pointer to another file.

Key points:

There are several types of file links.
Depending on the link type, the link may or may not be automatically followed during a file operation.
Some file link types are used to mount sub-volumes.
The link property is ALWAYS accessed on the LINKING file.
A link is defined by its type and any number of type-specific parameters.
File links are either static or dynamic.

Examples:

path /gallery/smile.jpg
package example.com 01ed8bb7a8ad5500c8885da1575f77068d0777606d
volume
scope

Follow a link

To follow a link is to get the linked file - if it exists.

Link type

A file's link type defines how Boomla treats the link during file operations.

Available link types and their main properties:

Link type	Static / Dynamic	Transparent	Filesystem scope	Mounts volume
`package`	static	yes	yes	yes, read-only
`scope`	static	yes	yes	yes, read/write
`volume`	static	yes	no	yes, read/write
`path`	dynamic	no	no	no

Package link

A package link is a file link mounting a package by its hash. The package link is a static link: the mounted subtree becomes part of the website and remains there even if the original package website is removed.

Example: package example.com 01ed8bb7a8ad5500c8885da1575f77068d0777606d

Path link

A path link is a reference to another file by an internal path. It is not automatically followed. Its only purpose is documenting the relationship between the two files. The path link is a dynamic link.

Example: path /foo/bar

Scope link

A scope link mounts a writable volume that establishes a filesystem scope. The scope link is a transparent, static link.

Turn a package link into a scope link to make it editable. (This will also prevent the system from updating the package.)

Example: scope

Simple volume

A simple volume is a volume linked via a volume link.

Static link

A static link mounts another volume by its hash. The mounted volume is part of the filesystem and the link can not break.

Modifying a statically mounted volume causes hash change propagation in the linking volume.

Transparent link

A link is said to be a transparent link if it lets you transparently read and write the linked file's data except the following:

name,
file hash,
subtree size,
fileId,
fileNodeId,
link.

The rest of the file's data is accessed on the LINKED file:

type,
title,
status code,
attributes,
body,
children,
created, createdBy,
modified, modifiedBy,
subtreeModified, subtreeModifiedBy.

For example, a volume link is a transparent link, while a path link is not.

Volume link

A volume link mounts a volume with no special properties except for being a separate fileNodeId space. It is a transparent, static link.The attached volume is also called a simple volume.

Example: volume
