Welcome to APIS’s documentation!


The APIS project intents to semantically annotate the Austrian Bibliography Lexicon (ÖBL). To achieve this goal we develop(ed) this web-app. It is based on a 5 entities (person, place, institution, event, work) data model. All 5 entities are connected to each other. Entities, as well as relations between them, can be typed with vocabularies similar to the Simple Knowledge Organization System (SKOS).

While a default APIS installation uses the 5 entities data model described above, this data model can be rather easily adapted to whatever fits best to the project using it. Frontend and RestAPI automatically adapt to changes in the data model.

In addition to this configurable import of data via RDF, there is also an configurable serialization of data. The generic RestAPI of APIS provides data either in the internal JSON format, TEI or RDF (serialized with CIDOC CRM).

APIS comes with a built in system of autocompletes that allows researchers to import meta-data of entities with just a single click. Out of the box APIS supports Stanbol as a backend for the autocompletes, but the system is rather easy to adapt to any Restfull API. APIS also supports the parsing of RDFs describing entities into an entity. The parsing is configured in a settings file.

APIS has a mnodular structure and its core functionalities (provided by this library) can be extended with further modules. Currently there are:

  • apis-highlighter: apis-highlighter provides offset annotation features to apis-core. It can be used to annotate any text stored in APIS and link the annotations to any object in APIS (entities, relations, vocabularies…). The forms used to create relations, entities etc. can be reused in the highlighter and annotators can create entities and annotations in one step. The annotations can also be organized in so-called annotation projects and provided to frontends via the API. Forms and context menus can be configured in the admin backend.

  • apis-bibsonomy: apis-bibsonomy provides the possibility to add bibliographic references to either whole objects or single attributes of these objects. As a backend for managing these bibliographic references one can use either zotero_ or bibsonomy_.

For a demo of the application please refer to apisdev.

Install the package

things which needs to be added to the project’s settings and urls files

# mandatory:

## add apis-apps to INSTALLED_APPS


‘apis_core.apis_entities’, ‘apis_core.apis_metainfo’, ‘apis_core.apis_relations’, ‘apis_core.apis_vocabularies’, ‘apis_core.apis_labels’, … ```

## add apis specific context_processors

``` ‘OPTIONS’: {

‘context_processors’: [

… ‘webpage.webpage_content_processors.is_dev_version’, ‘apis_core.context_processors.custom_context_processors.add_entities’, …





configure the default columns for entitiy list views

‘table_fields’: [

‘name’, ‘lat’, ‘lng’



configure which columns users can add to the default list view

‘additional_cols’: [

‘lat’, ‘lng’, ‘part_of’



## Filter configuration for Relation Views

Filters for list views for apis relations are generated by apis_core.apis_relations.rel_filters.get_filters and can be configured via specific settings parameters in the project’s settings file. You can provide a list APIS_RELATIONS_FILTER_EXCLUDE with (sub)strings of field names which should be excluded from the filter.

The list below provides a reasonable default:


‘uri’, ‘tempentityclass’, ‘user’, ‘__id’, ‘source’, ‘label’, ‘temp_entity’, ‘collection__’, ‘_ptr’, ‘baseclass’, ‘id’, ‘written’, ‘relation_type__description’, ‘relation_type__parent_class’, ‘relation_type__status’, ‘relation_type__vocab_name’, ‘relation_type__name_reverse’, ‘__text’,


Additionally you can exclude fields on class level:


‘PersonPlace’: {

‘exclude’: [‘name’]



# optional:


In case you set this parameter to False then apis_core.apis_metainfo.TempEntityClass.get_prev_url() and apis_core.apis_metainfo.TempEntityClass.get_next_url() methods return False. Set this param to deactivate the prev/next browsing function in the entitie’s detail view. Default (if not set) is True


This parameter is used to construct URIs for Apis Entities in case no external URIs (like geonames or gnd) are provided, defaults to http://apis.info

e.g. APIS_BASE_URI = ‘https://myprocect/objects/’ will create a URI like https://myprocect/objects/1234

## log-in-restrictions If theese settings are missing or set to False not logged in users will be redirected to log-in page


## Override the entities’ list view template:

Change the template name in the project’s settings file by adding the following variable

APIS_LIST_VIEW_TEMPLATE = “browsing/generic_list.html” APIS_DELETE_VIEW_TEMPLATE = “webpage/confirm_delete.html”

## TEI

In case you store TEI encoded XML in you TEXT objects, you can display those with https://github.com/TEIC/CETEIcean. Therefore you’ll need to list the values of Text.kind.name in a settings parameter. Let’s say that all TEI texts are stored in Text fields with kind “xml/tei transcription”:

APIS_TEI_TEXTS = [‘xml/tei transcription’]

You’ll also need to set define the locations for the CETEICEAN specific static files via dedicated paramters:

` APIS_CETEICEAN_CSS = "http://teic.github.io/CETEIcean/css/CETEIcean.css" APIS_CETEICEAN_JS = "http://teic.github.io/CETEIcean/js/CETEI.js" `


In case you want to dipslay images served via IIIF protocoll add the following params to your settings files

` APIS_IIIF_WORK_KIND = 'IIIF' APIS_IIIF_ENT_IIIF_REL = "has iiif image" APIS_IIIF_SERVER = "https://iiif.acdh.oeaw.ac.at/" # APIS_OPENSEADRAGON_CSS = "https://teic.github.io/CETEIcean/css/CETEIcean.css" APIS_OSD_JS = "https://cdnjs.cloudflare.com/ajax/libs/openseadragon/2.4.0/openseadragon.min.js" APIS_OSD_IMG_PREFIX = "https://cdnjs.cloudflare.com/ajax/libs/openseadragon/2.4.0/images/" `

custom management commands

python manage.py import_rel_vocabs {path-to-excel-file}

Excel-File needs to match following conventions:

sheet name needs to be the class name of the Vocab class, e.g. PersonWorkRelation

sheets need column-header ebene_1, ebene_2, … field values: name|name_reverse; if no name_reverse value is provided, name_reverse is the same as name all vocabs in one row are linked with as parent_classes, column one does not have a parent class, column 2 (ebene_2) takes as parent value from class ebene_1
