Inside the bundle, the entry point is a file called "manifest.ttl". +# This file lists what plugins are in this bundle, and which files are (.so, +# .ttl, etc.) are associated with those plugins. +# +# Hosts read bundles' manifest.ttl to discover what plugins (and other +# resources) are available. Manifest files should be as small as possible for +# performance reasons. +# +# The syntax of this file (and most other LV2 data files) is a language called +# Turtle ("Turse RDF Triple Language").[1] RDF[3] is a data model that +# expresses the relationship between things as (subject, predicate, object) +# triples. Turtle is a simple, terse, abbreviated syntax for RDF. + +# Namespace Prefixes + @prefix lv2: <http://lv2plug.in/ns/lv2core#> . @prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> . +# Data (list of resources in this bundle, hence "manifest") + <http://lv2plug.in/plugins/eg-amp> a lv2:Plugin ; lv2:binary <amp.so> ; rdfs:seeAlso <amp.ttl> . + +# Explanation +# +# In short, this declares that the resource with URI +# "http://lv2plug.in/plugins/eg-amp") is an LV2 plugin, with executable code in +# the file "amp.so" and a full description in "amp.ttl". These paths are +# relative to the bundle directory. +# +# There are 3 statements in this description: +# +# # | Subject | Predicate | Object +# ------------------------------------------------------------------- +# 1 | <http://lv2plug.in/plugins/eg-amp> | a | lv2:Plugin +# 2 | <http://lv2plug.in/plugins/eg-amp> | lv2:binary | <amp.so> +# 3 | <http://lv2plug.in/plugins/eg-amp> | rdfs:seeAlso | <amp.ttl> +# +# The semicolon is used to continue the previous subject, an equivalent +# but more verbose syntax for the same data is: +# +# <http://lv2plug.in/plugins/eg-amp> a lv2:Plugin . +# <http://lv2plug.in/plugins/eg-amp> lv2:binary <amp.so> ; +# <http://lv2plug.in/plugins/eg-amp> rdfs:seeAlso <amp.ttl> . +# +# Note that the documentation for a URI can often be found by visiting that URI +# in a web browser, e.g. the documentation for lv2:binary can be found at +# <http://lv2plug.in/ns/lv2core#binary>. If you encounter a predicate in some +# data which you do not understand, try this first. +# +# Note the URI of a plugin does NOT need to be an actual web address, it's just +# a global identifier. It is, however, a good idea to use an actual web +# address if possible, since it can be used to easily access documentation, +# downloads, etc. Note there are compatibility rules for when the URI of a +# plugin must be changed, see the LV2 specification[4] for details. +# +# A detailed explanation of each statement follows. +# +# 1: <http://lv2plug.in/plugins/eg-amp> a lv2:Plugin +# +# The "a" is a Turtle shortcut for rdf:type and more or less means "is a". +# lv2:Plugin expands to <http://lv2plug.in/ns/lv2core#Plugin> (using the +# "lv2:" prefix above) and is the established URI for the type "LV2 Plugin". +# This statement literally means "this resource is an LV2 plugin". +# +# 2: <http://lv2plug.in/plugins/eg-amp> lv2:binary <amp.so> +# +# This says "this plugin has executable code ("binary") in the file +# named "amp.so", which is located in this bundle. The LV2 specification +# defines that all relative URIs in manifest files are relative to the bundle +# directory, so this refers to the file amp.so in the same directory as this +# manifest.ttl file. +# +# 3: <http://lv2plug.in/plugins/eg-amp> rdfs:seeAlso <amp.ttl> +# +# This says "there is more information about this plugin located in the file +# "amp.ttl". The host will look at all such files when it needs to actually +# use or investigate the plugin. + +# Footnotes +# +# [1] http://www.w3.org/TeamSubmission/turtle/ +# [2] http://www.w3.org/RDF/ +# http://www.w3.org/TR/2004/REC-rdf-primer-20040210/ +# [3] http://tools.ietf.org/html/rfc3986 +# [4] http://lv2plug.in/ns/lv2core
