NAME Dancer::Plugin::Catmandu::SRU - SRU server backed by a searchable Catmandu::Store SYNOPSIS #!/usr/bin/env perl use Dancer; use Catmandu; use Dancer::Plugin::Catmandu::SRU; Catmandu->load; Catmandu->config; my $options = {}; sru_provider '/sru', %$options; dance; DESCRIPTION Dancer::Plugin::Catmandu::SRU is a Dancer plugin to provide SRU services for Catmandu::Store-s that support CQL (such as Catmandu::Store::ElasticSearch). Follow the installation steps below to setup your own SRU server. REQUIREMENTS In the examples below an ElasticSearch 1.7.2 https://www.elastic.co/downloads/past-releases/elasticsearch-1-7-2 server will be used: $ cpanm Dancer Catmandu::SRU Catmandu::Store::ElasticSearch $ wget https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.2.zip $ unzip elasticsearch-1.7.2.zip $ cd elasticsearch-1.7.2 $ bin/elasticsearch RECORDS Records stored in the Catmandu::Store can be in any format. Preferably the format should be easy to convert into an XML format. At a minimum each record contains an identifier '_id'. In the examples below we'll configure the SRU to serve Dublin Core records: $ cat sample.yml --- _id: 1 creator: - Musterman, Max - Jansen, Jan - Svenson, Sven title: - Test record ... CATMANDU CONFIGURATION ElasticSearch requires a configuration file to map record fields to CQL terms. Below is a minimal configuration required to query for '_id' and 'title' and 'creator' in the ElasticSearch collection: $ cat catmandu.yml --- store: sru: package: ElasticSearch options: index_name: sru bags: data: cql_mapping: default_index: basic indexes: _id: op: 'any': true 'all': true '=': true 'exact': true field: '_id' creator: op: 'any': true 'all': true '=': true 'exact': true field: 'creator' title: op: 'any': true 'all': true '=': true 'exact': true field: 'title' IMPORT RECORDS With the Catmandu configuration files in place records can be imported with the catmandu command: # Drop the existing ElasticSearch 'sru' collection $ catmandu drop sru # Import the sample record $ catmandu import YAML to sru < sample.yml # Test if the records are available in the 'sru' collection $ catmandu export sru DANCER CONFIGURATION The Dancer configuration file 'config.yml' contains basic information for the Catmandu::SRU plugin to work: * store - In which Catmandu::Store are the metadata records stored * bag - In which Catmandu::Bag are the records of this 'store' (use: 'data' as default) * cql_filter - A CQL query to find all records in the database that should be made available to SRU * default_record_schema - The metadataSchema to present records in * limit - The maximum number of records to be returned in each SRU request * maximum_limit - The maximum number of search results to return * record_schemas - An array of all supported record schemas * identifier - The SRU identifier for the schema (see L) * name - A short descriptive name for the schema * fix - Optionally an array of fixes to apply to the records before they are transformed into XML * template - The path to a Template Toolkit file to transform your records into this format * template_options - An optional hash of configuration options that will be passed to L or L
