Dynamic Collections Through Annotation

Combining remote resources into useful, curated Collections can be difficult. IIIF describes the look of these collections, but they are usually hosted by the same repository as the included items. Ong CDH has implemented two different methods for creating changeable collections that can be used by researchers and programmers alike. Demonstrations will include real resources […]

Building a IIIF-Aware Ecosystem

OngCDH would not be able to operate as lean as it does without a convenient foundation of tools to work access, manipulate, and create IIIF and Web Annotation compliant Objects. The existence of the standard has allowed for useful tools for application logic, such as Manifest in the IIIF-Commons, but we have extended this usefulness […]

Geolocating with IIIF Presentation API 2.1 Annotation

The experience with Annotation during the initial phases of implementing this syntax was positive. We found it prudent to investigate Annotation again using IIIF Presentation API 3.0. Implementation Description Below you will see an empty Manifest geolocated via a geographic polygon. There is an Annotation Page containing a single Annotation with coordinates to central Paris, […]

Geolocating with IIIF Presentation API 3.0: Part 3

Having found success with IIIF Presentation API 3 Annotation, we look to see if services can support GeoJSON-LD. Implementation Description Below you will see an empty Manifest geolocated via a GeoJSON service. The body of that service is a GeoJSON-LD Point. Example JSON { “@context”:[ “http://geojson.org/geojson-ld/geojson-context.jsonld”, “http://iiif.io/api/presentation/3/context.json” ], “id”:”http://www.example.org/manifest/3″, “type”:”Manifest”, “label”:{ “en”:[ “Example IIIF Presentation […]

Geolocating with IIIF Presentation API 3.0: Part 2

Annotation was successful during the first phase of using IIIF Presentation API 3.0 for geolocating an entire Web entity.  Another piece is to ensure that we could provide geolocated assertion upon an entity fragment, since situations like inset maps are common and need specific geospatial information that does not apply to the entire entity. Implementation […]

Geolocating with IIIF Presentation API 2.1 Services

The shortcomings of the Annotation syntax meant looking for another option. The other option of intertwining syntax is IIIF Presentation API 2.1 services. Initial investigation led to a supported GeoJSON extension, which meant there was already a foundation set for working with GeoJSON under the scope of the API. Implementation Description Below you will see […]

IIIF Cookbook: Data Recipes For Humans

As with any standards committee or best practices group, there is a subgroup tasked with providing examples for the internal community as well as external implementers.  For IIIF, this group is the Cookbook group.  Examples exist in the public Cookbook that properly format data assertions and combine them with resources in order to enhance those resources.  […]

IIIF and Maps Conference: Coordinates in Data

The OCDH has been involved with the International Image Interoperability Framework™ (IIIF) since its beginning.  We are adept with Annotation to supply supplementary data to data resources that are owned by others.  We have our own public open annotation store and Web API known as RERUM to support this ecosystem of assertions.  The scope of IIIF encompasses […]

Maps and Humanities

It should not be a surprise that data describing humanity depends heavily on the dimensions of time and space.  How else can data representing human interaction, error, rectification, discovery, or adventure exist without these dimensions?  The human construct of reality stands on concepts that give bounds to infinity.  Time and space afford humans the concepts of […]
