# K10plus DDC
This repository contains scripts to analyze, convert and publish Dewey Decimal Classification (DDC) numbers found K10plus catalogue. The analysis is mainly based on [coli-ana] DDC number decomposition.
[coli-ana]: https://github.com/gbv/coli-ana
[K10plus Subjects]: https://github.com/gbv/k10plus-subjects
[jskos]: https://format.gbv.de/jskos
**See subdirectory `publication` for script to generate the data publication **
## Installation
~~~sh
npm ci
~~~
## Usage
### analyze.js
Read a list of (numerically sorted) DDC numbers and generate analysis with coli-ana
#### k10plus-patch.js
The script `bin/k10plus-patch.js`
1. reads PICA+ records (or PPNs to retrieve records from K10plus)
2. extracts DDC fields from the records
3. retrieves DDC analysis (cached in a local database)
4. and emits [PICA Patch](https://format.gbv.de/pica/patch/specification) files to modify records
~~~
Usage: k10plus-patch [options] < file
Check and extend DDC numbers in PICA records of K10plus catalogue
Options:
-a, --api coli-ana API endpoint
-c, --continue continue after given PPN (expect sorted)
-f, --format PICA+ serialization (default: plain)
-i, --input input file (default: - for STDIN)
-d, --database optional SQLite file for caching
-p, --ppns input is list of PPNs instead of PICA records
-h, --help display help for command
~~~
### simplify-for-pdf.jq
Given the full analysis from coli-ana API in JSKOS format as published at
, this jq script can be used to
simplify the JSKOS records for creation of PDF files for each DDC number:
~~~sh
zcat ddc-decomposition.ndjson.gz | jq -c -f simplify-for-pdf.jq -c > ddc-pdf-data.ndjson
~~~
### count.js
Calculate frequency of individual DDC elements in analysis result and emit as CSV or JSKOS concept list
## Data in this repository
- `ddcs` sorted DDC numbers found in K10plus with number of occurrences. Data generated from [K10plus Subjects].
