Help with syntax ... Object::InsideOut

[jps]

Hi!

I am trying to grasp the "design pattern" of Object::InsideOut and was
reading this:
http://search.cpan.org/~jdhedden/Object-InsideOut-3.52/lib/Object/InsideOut.pod

Looking at the code-examples, I see things like

my @data
:Field
:Type(numeric)
:Accessor(data);

and

sub init :Init

etc.

What are these syntactic elements ":Field" and ":Init" ?
And what do they mean?

I cannot remember having seen those ":Xxxx" constructs before...
What do you call these elements, so I know what to google for?

Thanks for help!

They are called attributes.

There are some built-in attributes as well:
