Rule metadata are key-value pairs where the value is a simple (atomic) string or number.
meta(x, ...)meta(x, name) <- value
# S4 method for rule
meta(x, ...)
# S4 method for rule,character
meta(x, name) <- value
# S4 method for expressionset
meta(x, simplify = TRUE, ...)
# S4 method for expressionset,character
meta(x, name) <- value
an R object
Arguments to be passed to other methods
[character] metadata key
Value to set
Gather all metadata into a dataframe?
Other expressionset-methods:

created(),
description(),
label(),

origin(),
plot,validator-method,
summary(),
variables(),
voptions()
v <- validator(x > 0, y > 0)
# metadata is recycled over rules
meta(v,"foo") <- "bar"
# assign metadata to a selection of rules
meta(v[1],"fu") <- 2
# retrieve metadata as data.frame
meta(v)
# retrieve metadata as list
meta(v,simplify=TRUE)
