Manifest Metadata Processor

This is a collection of APIs for the manipulation of IIIF Manifests

Requirements

JDK 11

Reserializer

This is an api to change/correct previously published manifests. It can also produce version 3 manifests from version 2 data. If new metadata is available via a JSON API, it can modify existing labels and values.

Parameters

Name	Options	Description
type	reserialize	processor type
m	(none)	the URI of a IIIF (v.2.1) manifest
version	2 or 3	the IIIF output specification

 http://localhost:9098/extractor?type=reserialize&version=3&m={$remote_manifest_URI}

Renderer

This is an api that can produce a zip file or PDF of a range of images from a IIIF manifest:

Parameters

Name	Options	Description
type	pdf, image	serialization options
manifest	(none)	the URI of a IIIF (v.2.1) manifest
from	(none)	the first index of the image sequence
to	(none)	the last index of the image sequence
pct	(none)	the scale of the images (as a percentage)

Example

http://localhost:9099/renderer?type=pdf&manifest=http://iiif.ub.uni-leipzig.de/0000009000/manifest.json&from=1&to=30&pct=25`

Preflight for Image Count

A client can get the image count in a manifest with this request:

http://localhost:9099/renderer?type=count&manifest=http://iiif.ub.uni-leipzig.de/0000009000/manifest.json

The response is a JSON Object

{
  "imageServiceCount" : 316
}

Docker Compose

The service can be deployed with this:

$ cd src/main/resources/renderer
docker-compose up

Extractor

This provides an Camel Jetty API that can be crawled by an httpclient to get indexable JSON documents containing mapped metadata fields sourced from IIIF manifests.

http://localhost:9098/extractor?type=extract&manifest={$remote_manifest_URI}

The client can then use the elasticsearch API and PUT the response bodies into an index for discovery. See IndexerCrawlerTest for an example.

Indexer

(WIP)

ElasticSearch

See docs for sample analysis data from Elastic.

This gets all manifest URIs and their title from the index.

curl -XGET "http://localhost:9100/m1/_search" -H 'Content-Type: application/json' -d'
{
    "_source": ["metadataMap.@id", "metadataMap.Title"],
    "from" : 0, "size" : 10000,
    "query" : {"match_all" : {}}
}'

Host requires this:

$ sudo sysctl -w vm.max_map_count=262144

• Start elasticsearch-compose

Kibana

• The Kibana interface can be accessed at http://localhost:5601
