Each Databus Artifact represents one certain ontology and each version represents a new version of the ontology.\n\n## Use Cases\n\n* **Ontology-Backup:** From time to time ontologies are unavailable at their usual location in the web. In this case Archivo can be used as a simple backup to prevent failure of services.\n* **Testing \u0026 Rating:** Archivo runs some test to check the usability of a ontology, for example parsing, licenses or consistency. For this Archivo introduced a [star-rating](#Stars). \nCheck out \u003chttp://archivo.dbpedia.org/info\u003e for a detailed view of the versions of each ontology with the test results.\n\n## Accessing an Ontology (Version) via Archivo\n\n### Simple\nTo download the latest version use \n\n`http://archivo.dbpedia.org/download?o={ontology-URI}\u0026f={file-extension}`\n\nand Archivo redirects to the latest version that is backed up.\n\nThe format can be set by using `f={ttl,owl,nt}` (optional, default: owl) or by setting the Accept-Header (first one overwrites the latter).\n\n**Example:**\n`curl -L \"http://archivo.dbpedia.org/download?o=http://advene.org/ns/cinelab/ld\u0026f=ttl\"`\ndownloads the latest version of the Cinelab ontology as Turtle file.\n\n### Advanced\n\nBy using a GET request with the implemented formats (`application/rdf+xml`, `application/n-triples` or `text/turtle`) as Accept-Headers returns all information about all versions of this URI as RDF.\n\n## Browse, Find and Search Ontologies included in Archivo\n\nThere are multiple options to find an ontology (snapshot):\n\n* [Here](http://archivo.dbpedia.org/list) is a complete list of all ontologies in Archivo with their Databus Artifact and the URL of the latest Turtle-File of each.\n* Enter your ontology-URI [here](http://archivo.dbpedia.org/info) and you get information about all the versions of the ontology archived in Archivo.\n* Check out the the handy collections on the DBpedia Databus:\n    * A collection of the latest original files: [here](https://databus.dbpedia.org/jfrey/collections/archivo-latest-original-ontology-snapshots)\n    * A collecttion of the latest parsed files: [here](https://databus.dbpedia.org/jfrey/collections/archivo-latest-ontology-snapshots)\n\n## Adding an Ontology to Archivo\n\nOntologies can be added to Archivo using the [add-service](http://archivo.dbpedia.org/add) of the frontend. But the ontology must fulfill two requirements to be added:\n* The URI must be accessible and the RDF content of the ontology must be reachable via content negotiation from there in any of these formats: RDF+XML, N-Triples, Turtle\n* The URI defined in the a owl:Ontology (or skos:ConceptScheme) triple must be the same as the one provided here. If that's not the case Archivo tries to handle the new URI just like the one entered.\n\n## Star Rating\n\nArchivo provides a basic star-rating (not to be confused with the 5 stars of linked data).\n\nBaseline: The minimum requirements a Ontology should fulfill.\n\n* All  of  the  following  criteria  have  to  be  fulfilled:\n    1) The non-information URI resolves to a machine readable format or a machine readable version of the ontology is deterministically discoverable by other common means. \n    2) Download was successful \n    3) Uses a common format implemented by Archivo (rdf+xml, turtle or n-triples)\n    4) At least one format was found that parses with no or few (negligible) syntactical warnings\n\n* A proper ontology declaration was found using `rdf:type owl:Ontology` and some form of license could be detected. A high degree of heterogeneity is permissible for this star regarding the used property/subproperty as well as  object:license  URI  (resolvable  linked  data  or  web  link),xsd:stringorxsd:anyURI\n\nIf the ontology fulfills the baseline, it can earn two further stars by using good practises:\n\n* We require a homogenized license declaration using `dct:license` as object property with a URI (not string or anyURI). \n\n* We measure the compatibility with currently available reasoners such as Pellet/Stardog (more to follow) and run available tasks such as consistency checks and classification.\n\n## Archivo Documentation\n\n\n### Augmentation Files (on the Databus)\n\nArchivo provides for each version different files:\n\n| type-values | sub-cvs | Explaination |\n| -------- | -------- | -------- |\n| orig     |      | Snapshot of the original ontology file |\n| parsed   |      | Files parsed by rapper, available as owl, nt and ttl |\n| OOPS     |      | OOPS-report |\n| generatedDocu | | human readable documentation by LODE |\n| profile | | a profile check done by [profilechecker](https://github.com/stain/profilechecker)|\n| shaclReport | validates={minLicense, goodLicense, lodeMetadata} | shacl-report as turtle file|\n| meta | | a JSON file containing some meta info |\n| pelletInfo | imports={FULL,NONE} | the pellet info report, with and without imports |\n| pelletConsistency | imports={FULL,NONE} | the pellet consistency report, with and without imports |\n| diff | axioms={old,new} | These file contain the added/deleted triples | \n\n\n### Ontology Sources\n\nArchivo uses four different sources to find potential ontologies:\n\n1. Ontology Repositories: e.g ontologies listed in [LOV](https://lov.linkeddata.es/dataset/lov/)\n2. Subjects, Predicates and Objects of Ontologies: Every SPO in an Ontology can lead to a potential new ontology, so Archivo can discover new vocabularies by analyzing already listed ontologies\n3. [VOID](https://www.w3.org/TR/void/) Data: Search for new ontologies by looking at VoID metadata summaries describing used classes and properties (on the DBpedia Databus) \n4.
