Art::World - Modeling of creative processes


  use Art::World;

  my $artwork = Art::World->new_artwork(
    creator => [ $artist, $another_artist ]  ,
    value   => 100,
    owner   => 'smonff' );

  my $museum = Art::World->new_museum(
    money => 1000,
    name  => 'Contemporary Museum of Art::World'

  $museum->acquire( $artwork );


Art::World is an attempt to model and simulate a system describing the interactions and influences between the various agents of the art world.

It tries to draw a schematization of the interactions between art, institutions, influences and unexpected parameters during the social processes of artistic creation.

More informations about the purposes and aims of this project can be found in it's Art::World::Manual. Especially, the HISTORY and the OBJECTIVES section could be very handy to understand how this is an artwork using programming.


This project is a self-teaching experiment around the modern Perl object-oriented programming toolkit. In late 2020, I read a bit about Corrina and immediatly wanted to restart and experiment my old Art::World project. While searching for something somewhat close to Corrina, since Corrina was only a draft and RFC, I discovered the Zydeco toolkit by Toby Inkster and immediatly felt very enthusiastic to use it to implement my idea. I hope it is a decent example of the possibilities this wonderful framework make possible.



This is were all kind of weird phenomenons between abstract artistic entities happen. See the Manual about how it works.


Is used to dissociate behaviors belonging to performers as opposed to the public. Provide a participate method.


All this behavior and attributes are encapsulated in the Buyer role because there is no such thing as somebody in the art world that buy but doesn't sale.

The aquire method is requiring some money. The money is provided by the Market role.

  $collector->acquire( $artwork );

When a Collector acquire() an Artwork, the Artwork ArrayRef of owners is automatically cleared and substituted by the new owner(s). acquire() will remove the value of the Artwork from the owner's money.

Those behaviors are delegated to the private $change_owner() method, and to the pay() method from the Market role.


The collectionnable provide a series of attributes.

If it's collectionable, it can go to a Collector collection or in a Museum. A collectionable item is automatically owned by it's creator.


The Crud role makes possible to serialize most of the entities. For this to be possible, they need to have a corresponding table in the database, plus they need to not have a unserializable? tag attribute. A Zydeco tag role is a role without behavior that can only be checked using does.

The Crud role is made possible thanks to Teng, a simple DBI wrapper and O/R Mapper. Teng is used through it's schema loader that directly instanciate an object schema from the database.

When trying to update a value, it is necessary to pass a table name and a hashref of attributes. The table name is not case sensitive.

Note that it is extremely important that the testing of the database should be done in the t/crud.t file. If you want to test database or model functionnalities in other tests, remind to create objects by specifiying the config parameter that use the test.conf file: only the database referenced in test.conf will be available on cpantesters and art.db wont be available there, only t/test.db is available.


All the necessary attributes and methodes for having fun between Art::world's Agents.


Role for Places that display some Artworks.


Fame role provide ways to control the aura and reputation that various Agents, Places or Works have. Cannot be negative.

It has an handy bump_fame() method that self-bump the fame count. It can be used in three specific maneers:

pass a PositiveNum

The fame will go higher

pass a NegativeNum

The fame he fame will go lower

no parameter

In that case the value defined by $self->config->{ FAME }->{ DEFAULT_BUMP } will be used to increase the reputation.

  my $artist = Art::World->new_artist(
    reputation => 0.42,
    name => 'Questular Rontok'

  say $artist->bump_fame;               # ==>  1.42
  say $artist->bump_fame( 0.0042 );     # ==>  1.4242

If you try to update the fame to a negative value, nothing happens and a nice warning is displayed.

The fame can be consummed by pretty much everything. A Place or and Agent have a fame through it's reputation, and an Artwork too through it's aura.

Classes that consume Fame can have two different kind of attributes for storing the Fame:


For Works only.


For Agents, Places, etc.


It is all about offer and demand. Involve money. It provide a pay() method that can be using by entities consumming this role. This method accept an Artwork as an unique required parameter.


A role for those who take care of exhibitions and other organizational matters. See how being a Manager influence an Agent in the CLASSES section.


Only an object that does the Showable role can be exhibited. An object should be exhibited only if it reached the Showable stage.



They are the activists of the Art World, previously known as the Wildlife.

  my $agent = Art::World->new_agent( name => $f->person_name );

  $agent->participate;    # ==>  "That's interesting"

A generic entity that can be any activist of the Art::World. Provides all kind of Agent classes and roles.

The Agent got an a networking( $people ) method. When it is passed and ArrayRef of various implementation classes of Agents (Artist, Curator, etc.) it bumps the reputation attributes of all of 1/10 of the Agent with the highest reputation. If this reputation is less than 1, it is rounded to the $self->config->{ FAME }->{ DEFAULT_BUMP } constant.

The bump coefficient can be adjusted in the configuration through { FAME }->{ BUMP_COEFFICIENT }.

There is also a special way of bumping fame when Managers are in a Networking activity: The influence() method makes possible to apply the special $self->config->{ FAME }->{ MANAGER_BUMP } constant. Then the Agents reputations are bumped by the MANAGER_BUMP value multiplicated by the highest networking Manager reputation. This is what the influence() method returns:

  return $self->config->{ FAME }->{ MANAGER_BUMP } * $reputation;

The default values can be edited in art.conf.


Will be what you decide it to be depending on how you combine all the entities.


Something in a Magazine of Website about Art, Exhibitions, etc.


In the beginning of their carreer they are usually underground and produce experimental art, but this can change in time.

  my $artist = Art::World->new_artist(
    name => 'Andy Cassrol',

  say $artist->is_homogenic;
  #==> false

After getting collected, artists become homogenic.

  $artist->is_underground if not $artist->has_collectors;

The artist got a lots of wonderful powers:


When the basic abstractions of Art are articulated, a creation occurs. It doesn't mean that it will create an Artwork, because it requires the intervention of other Agents. The Artist creates through a work concept. This articulation can group the different attributes of the Abstraction role: discourse, file, idea, process, project and time.

have_idea all day long


The base thing producted by artists. Artwork is subclass of Work that have a Showable and Collectionable role.


Where a lot of theory is written by Critics



They do stuff together. You know, art is not about lonely Artists in their Workshop.


Concept is an abstract class that does the Abstraction role.



A special kind of Agent that can select Artworks, define a thematic, setup everything in the space and write a catalog.


An Event that is organised by a Curator.

Just another kind of Place, mostly commercial.

Since it implements the Buyer role, a gallery can both acquire() and sell().


When some abstractions starts to become something in the mind of an Agent


A Place that came out of the Underground.



Yet another kind of Place, an institution with a lot of Artworks in the basement.



A Place must invite() all kind of Agents that produce Work or other kind of valuable social interactions. Depending of the total reputation of the Place it will determine it's underground status: when going out of the underground, it will become an institution.


A generic space where Art::World Agents can do all kind of weird things.





A place were art world agents are doing things. A squat that is not underground anymore become an institution.


When some abstract concept turns to some said or written stuff.



There are not only Artworks. All Agents produce various kind of work or help consuming or implementing Art.


A specific kind of Playground where you can build things tranquilly.
