| 2 | Installation of this extension follows the usual pattern:
|
|---|
| 3 |
|
|---|
| 4 | ./CASCADE-MAKE.sh
|
|---|
| 5 |
|
|---|
| 6 |
|
|---|
| 7 | For interative experiments with the Triplestore, you can then visit
|
|---|
| 8 | the home page:
|
|---|
| 9 |
|
|---|
| 10 | http://localhost:3030/
|
|---|
| 11 |
|
|---|
| 12 | Go to the control panel:
|
|---|
| 13 |
|
|---|
| 14 | http://localhost:3030/control-panel.tpl
|
|---|
| 15 |
|
|---|
| 16 | The control panel lets you choose which dataset to work with through a
|
|---|
| 17 | drop-down menu. For the Greenstone extension installation there
|
|---|
| 18 | should only be one:
|
|---|
| 19 |
|
|---|
| 20 | /greenstone
|
|---|
| 21 |
|
|---|
| 22 | Pressing 'select' triggers a POST action to:
|
|---|
| 23 |
|
|---|
| 24 | http://localhost:3030/$/dataset
|
|---|
| 25 |
|
|---|
| 26 | which triggers a redirect (through setting 'Location:' in the respose header) to:
|
|---|
| 27 |
|
|---|
| 28 |
|
|---|
| 29 | http://localhost:3030/sparql.tpl
|
|---|
| 30 |
|
|---|
| 31 |
|
|---|
| 32 | A generic query to try out is:
|
|---|
| 33 |
|
|---|
| 34 | select * where { ?s ?p ?o } limit 100
|
|---|
| 35 |
|
|---|

|---|

|
|---|
| 40 |
|
|---|
| 41 | If serving your Greenstone3 through a public facing web server, such as Apache2,
|
|---|
| 42 | then the installed '.tpl' files and the Location redirects don't work. Introducing
|
|---|
| 43 | a base tag into the header such as:
|
|---|
| 44 |
|
|---|
| 45 | <base href="/greenstone3-lod/" />
|
|---|
| 46 |
|
|---|
| 47 | and changing the control-panel.tpl form action to be:
|
|---|
| 48 |
|
|---|
| 49 | <form action="/greenstone3-lod/${action}" method="post">
|
|---|
| 50 |
|
|---|
| 51 | helps a bit, but the Location redirect is still an issue.
|
|---|
| 52 |
|
|---|
| 53 | Bottom-line to run a SPARQL query directly, (for localhost) you would do:
|
|---|
| 54 |
|
|---|
| 55 | http://localhost:3030/greenstone/query?query=select+*+where+%7B+%3Fs+%3Fo+%3Fp+%7D+limit+100&output=text&stylesheet=
|
|---|
| 56 |
|
|---|
| 57 | For a proxied install you would (continuing the example) do:
|
|---|
| 58 |
|
|---|
| 59 | http://sowemustthink.space/greenstone3-lod/greenstone/query?query=select+*+where+%7B+%3Fs+%3Fo+%3Fp+%7D+limit+100&output=text&stylesheet=

| 63 | # Note about Jena code:
|
|---|
| 64 | #----
|
|---|
| 65 |
|
|---|
| 66 | Jena is a pure Java code base, and the relevant compiled jar files
|
|---|
| 67 | are bundled with this extension, so no actual compilation is needed.
|
|---|
| 68 | The main task CASCADE-MAKE.sh does is to untar the 'binary' files,
|
|---|
| 69 | and setup them up in appropriate top-level ' lib' folder (for jar
|
|---|
| 70 | files) etc so Greenstone can find them
|
|---|
| 71 |
|
|---|
| 72 | In case it is ever needed, the companion source code is in 'src'
|
|---|
| 73 | directory (taken from the Apache Jena website, matched to the binary
|
|---|
| 74 | version). For source code, there was only a zip version of the file
|
|---|
| 75 | to download.
|
|---|
| 76 |
|
|---|
| 77 | To run the command-line client programs, such as 's-put', this
|
|---|
| 78 | requires Ruby to be installed. The source code for this is
|
|---|
| 79 | provided in the 'packages' directory, and compiled up and installed
|
|---|
| 80 | as part of running ./CASCADE-MAKE.sh
|
