# RDF::DOAP(3pm)

an object-oriented interface for DOAP (Description of a Project) data

## NAME

RDF::DOAP - an object-oriented interface for DOAP (Description of a Project) data

## SYNOPSIS

```
   use feature 'say';
   use RDF::DOAP;

   my $url  = 'http://api.metacpan.org/source/DOY/Moose-2.0604/doap.rdf';
   my $doap = 'RDF::DOAP'->from_url($url);
   my $proj = $doap->project;

   say $proj->name;       # "Moose"

   say $_->name
      for @{ $proj->maintainer };
```

## DESCRIPTION

A little sparsely documented right now.

The RDF::DOAP class itself is mostly a wrapper for parsing RDF and building objects. Most of the interesting stuff is in the "Bundled Classes".

### Constructors

- "new(%attrs)"

  You don't want to use this.

- "from\_url($url)"

  Parse the RDF at the given URL and construct an RDF::DOAP object.

- "from\_file($fh, $base)"

  Parse a file handle or file name. A base URL may be provided for resolving relative URI references; if omitted the base is assumed to be `"http://localhost/"` which is almost certainly wrong.

- "from\_model($model)"

  Read DOAP from an existing RDF::Trine::Model.

### Attributes

- "projects"

  An arrayref; the list of software projects found in the input data. This cannot be provided in the constructor.

### Methods

- "project"

  If `"projects"` contains only one project, returns it.

  Otherwise, tries to guess which of the projects the input data was mostly trying to describe.

### Bundled Classes

Within each of these classes, the attributes correspond roughly to the properties defined for them in the DOAP schema; however hyphens in property URIs become underscores in attribute names.

- **RDF::DOAP::Resource**

  Correponds roughly to the *rdfs:Resource* class, excluding literals.

- **RDF::DOAP::Project**

  Correponds to *doap:Project*.

- **RDF::DOAP::Repository**

  Correponds to *doap:Repository*.

- **RDF::DOAP::Person**

  Correponds to *foaf:Person*.

- **RDF::DOAP::Version**

  Correponds to *doap:Version*.

- **RDF::DOAP::ChangeSet**

  Correponds to *dcs:ChangeSet*.

- **RDF::DOAP::Change**

  Correponds to *dcs:Change*.

- **RDF::DOAP::Issue**

  Correponds to *dbug:Issue*.
