A set of static assets used (mainly) for ARCHE data preprocessing

Project description

Arche Assets

PyPI version Latest Stable Version License

Set of static assets used (mainly) for ARCHE data preprocessing or ARCHE information pages:

  • URI normalization rules used within the ACDH-CD.
    (stored in AcdhArcheAssets/uriNormRules.json)
  • Description of input data formats accepted by ARCHE.
    (stored in AcdhArcheAssets/formats.json)

The repository provides also Python 3 and PHP bindings for accessing those assets.

Installation & usage

Python

  • Install using pip3:
    pip3 install acdh-arche-assets
    
  • Use with
    from AcdhArcheAssets.uri_norm_rules import get_rules, get_normalized_uri
    print(f"{get_rules()}")
    
    wrong_id = "http://sws.geonames.org/1232324343/linz.html"
    
    good_id = get_normalized_uri(wrong_id)
    print(good_id)
    # "https://www.geonames.org/1232324343"
    
    from AcdhArcheAssets.file_formats import get_formats, get_by_mtype, get_by_extension
    
    formats = get_formats()
    matching_mapping = get_by_mtype('image/png')
    matching_mapping = get_by_extension('png')
    

PHP

  • Install using using composer:
    composer require acdh-oeaw/arche-assets
    
  • Usage with
    require_once 'vendor/autoload.php';
    print_r(acdhOeaw\UriNormRules::getRules());
    print_r(acdhOeaw\ArcheFileFormats::getAll();
    print_r(acdhOeaw\ArcheFileFormats::getByMime('application/json');
    print_r(acdhOeaw\ArcheFileFormats::getByExtension('application/json');
    

Description of assets

Formats

A curated and growing list of file extensions. For each file extension mappings to the respective ARCHE Resource Type Category (stored in acdh:hasCategory) and Media Type (MIME type) (stored in acdh:hasFormat) are given. The indicated Media Type should only be used as a fallback; it is best practice to rely on automated Media Type detection based on file signatures.

Further information is provided as well.

  • fileExtension: File extension to be mapped.
  • name: Name(s) the format is known
  • archeCategory: The corresponding URI of the ARCHE Resource Type Category Vocabulary
  • dataType: A broad category to group formats in; mainly intended for visualisation purposes.
  • pronomID: ID(s) assigned by PRONOM
  • mimeType: Official Media Type(s) (formerly known as MIME types) registered at IANA.
  • informalMimeType: Other MIME types kown for the format
  • magicNumber: A constant numerical or text value used to identify a file format, e.g. Wikipedia list of file signatures
  • ianaTemplate: Link to template at IANA
  • reference: Link(s) to format specifications referenced by IANA and others
  • longTerm: Indicates if a format is suitable for long-term preservation.
    Possible values and their meaning
    • yes - long-term format
    • no - not suitable, another format should be used
    • restricted - can be used for long-term preservation in some cases (see comment)
    • unsure - status remains to be evaluated
  • archeDocs: Link to a place with more information for the format.
  • comment: Any other noteworthy information not stated elsewhere.
