...

1. Use fetcher in traditional /tika /rmeta endpoints

   1. update configs/tika-config-basic.xml <basePath> element to get the full path to tika-pipes-tutorial-20221202/docs:  

      Code Block
      language xml title FileSystemFetcher collapse true
      <fetcher class="org.apache.tika.pipes.fetcher.fs.FileSystemFetcher"> <params> <name>fsf</name>   <basePath>/Users/allison/Desktop/tika-pipes-tutorial-20221202/docs</basePath> </params> </fetcher>

      
      

   2. start the server: java -cp "server-bin/*" org.apache.tika.server.core.TikaServerCli -c configs/tika-config-basic.xml

   3. curl -X PUT http://localhost:9998/rmeta -H "fetcherName:fsf" -H "fetchKey:testPDF.pdf" | jq --sort-keys

2. Use /pipes handler to read from and write to a local file share

   1. update configs/tika-config-basic.xml <basePath> element to get the full path to tika-pipes-tutorial-20221202/docs:  

      Code Block
      language xml title FileSystemEmitter collapse true
      <emitters> <emitter class="org.apache.tika.pipes.emitter.fs.FileSystemEmitter"> <params> <name>fse</name> <basePath>/Users/allison/Desktop/tika-pipes-tutorial-20221202/extracts</basePath> </params> </emitter> </emitters>

      
      

   2. start the server: java -cp "server-bin/*" org.apache.tika.server.core.TikaServerCli -c configs/tika-config-basic.xml

   3. curl -X POST -H "Content-Type: application/json" -d @configs/pipes-request-minimal.json http://localhost:9998/pipes

3. Configure metadata filters and rerun 2.

   1. Copy this and paste it into configs/tika-config-basic.xml

      Code Block
      language xml title Metadata Filters collapse true
      <metadataFilters> <!-- depending on the file format, some dates do not have a timezone. This filter arbitrarily assumes dates have a UTC timezone and will format all dates as yyyy-MM-dd'T'HH:mm:ss'Z' whether or not they actually have a timezone. --> <metadataFilter class="org.apache.tika.metadata.filter.DateNormalizingMetadataFilter"/> <metadataFilter class="org.apache.tika.metadata.filter.FieldNameMappingFilter"> <params> <excludeUnmapped>true</excludeUnmapped> <mappings> <mapping from="X-TIKA:content" to="content_s"/> <mapping from="Content-Length" to="length_i"/> <mapping from="dc:creator" to="creators_ss"/> <mapping from="dc:title" to="title_s"/> <mapping from="Content-Type" to="mime_s"/> <mapping from="X-TIKA:EXCEPTION:container_exception" to="tika_exception_s"/> </mappings> </params> </metadataFilter> </metadataFilters>

      
      

   2. Restart the server
   3. Rerun the curl command and look at the output (cat extracts/testPDF.pdf.json | jq --sort-keys)
4. Use /async handler file share to file share

   1. curl -X POST -H "Content-Type: application/json" -d @configs/async-request-simple.json http://localhost:9998/async

   2. curl -X POST -H "Content-Type: application/json" -d @configs/async-request-full.json http://localhost:9998/async

5. Run the async processor via tika-app

   1. Configure the basePath element in FileSystemPipesIterator and FileSystemPipesIterator in configs/tika-config-app.xml

      Code Block
      language xml title FileSystemPipesIterator collapse true
      <fetcher class="org.apache.tika.pipes.fetcher.fs.FileSystemFetcher"> <params> <name>fsf</name> <basePath>/Users/allison/Desktop/tika-pipes-tutorial-2022120220211202/docs</basePath> </params> </fetcher> <pipesIterator class="org.apache.tika.pipes.pipesiterator.fs.FileSystemPipesIterator"> <params> <fetcherName>fsf</fetcherName> <emitterName>fse</emitterName> <basePath>/Users/allison/Desktop/tika-pipes-tutorial-2022120220211202/docs</basePath> </params> </pipesIterator>

      
      

   2. java -cp "app-bin/*" org.apache.tika.cli.TikaCLI -a --config=configs/tika-config-app.xml

6. Configure Solr/OpenSearch/ElasticSearch emitter and run /pipes handler

...

1. From the solr directory
   1. bin/solr start
   2. bin/solr create -c tika-example && bin/solr config -c tika-example -p 8983 -action set-user-property -property update.autoCreateFields -value false

2. From the tika-pipes-tutorial directory

   1. Set the schema in Solr: curl -F 'data=@configs/solr/solr-parent-child-schema.json' http://localhost:8983/solr/tika-example/schema

   2. Configure the basePath element in FileSystemPipesIterator and FileSystemFetcher in configs/solr/tika-config-solr.xml

      Code Block
      language xml title FileSystemPipesIterator collapse true
      <fetcher class="org.apache.tika.pipes.fetcher.fs.FileSystemFetcher"> <params> <name>fsf</name> <basePath>/Users/allison/Desktop/tika-pipes-tutorial-2022120220211202/docs</basePath> </params> </fetcher> ... <pipesIterator class="org.apache.tika.pipes.pipesiterator.fs.FileSystemPipesIterator"> <params> <fetcherName>fsf</fetcherName> <emitterName>solr1</emitterName> <basePath>/Users/allison/Desktop/tika-pipes-tutorial-2022120220211202/docs</basePath> </params> </pipesIterator>

      
      

   3. java -cp "app-bin/*" org.apache.tika.cli.TikaCLI -a --config=configs/solr/tika-config-solr.xml

...

1. Start opensearch via Docker:
   1. docker pull opensearchproject/opensearch:1.2.0
   2. docker run -p 9200:9200 -p 9600:9600 -e"discovery.type=single-node" opensearchproject/opensearch:1.2.0
2. Curl schema to opensearch: 

   curl -k -T configs/opensearch/opensearch-parent-child-mappings.json -u admin:admin -H "Content-Type:application/json" https://localhost:9200/tika-test

3. Configure the basePath element in FileSystemPipesIterator a nd FileSystemFetcher in configs/opensearch/tika-config-opensearch.xml

   Code Block
   language xml title FileSystemPipesIterator collapse true
   <fetcher class="org.apache.tika.pipes.fetcher.fs.FileSystemFetcher"> <params> <name>fsf</name> <basePath>/Users/allison/Desktop/tika-pipes-tutorial-2022120220211202/docs</basePath> </params> </fetcher> .... <pipesIterator class="org.apache.tika.pipes.pipesiterator.fs.FileSystemPipesIterator"> <params> <fetcherName>fsf</fetcherName> <emitterName>ose</emitterName> <basePath>/Users/allison/Desktop/tika-pipes-tutorial-2022120220211202/docs</basePath> </params> </pipesIterator>
