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 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 […]

A IIIF Concordance

As IIIF Manifests increasingly contain transcription annotations, the tools that are able to handle these documents must also treat text content as a first-class citizen. In our TPEN software, users regularly generate new annotations with text content that is included in the manifest documents made available for every project. In addition, TPEN allows for the […]

Exploiting Client-side Line Detection

Recently, two events coincided that inspired me to pull this code back out and take a second look at the process. The first is that our center charged a group of Computer Science majors with improving the effectiveness of our image processing algorithm as part of their senior capstone project; the second was the seemingly sudden burst of HTR promises, which depend on some level of layout analysis to work. In both cases, I was struck that improvements were accomplished in all cases with more processing power and additional layers of analysis.

Experimenting with Client-side Line Detection

Does not compute Using an “old” iPad on a plane to review transcription data was a clarifying task. For all the advances in research technologies, even simple tasks, such as viewing manuscript images on an institution’s website can crash a five year old browser, effectively rendering it inaccessible. I am not willing to accept that […]
