ilcd

This is a Go package for reading ILCD data sets. It currently supports only a subset of the ILCD format but allows very fast and memory efficient extraction of information from the different ILCD data set types.

Usage

Iterating over each data set in an ILCD package

The ilcd.ZipReader provides methods for extracting each data set of a specific type via the Each* functions:

zip, err := ilcd.NewZipReader("an_ILCD_package.zip")
// check err ...
err = zip.EachProcess(func(p *ilcd.Process) bool {
  fmt.Println(p.FullName("en"))
  return true // returning false will stop the iteration
})

Transforming and ILCD package

reader, err := ilcd.NewZipReader("input.zip")
check(err)
writer, err := ilcd.NewZipWriter("output.zip")
check(err)

reader.Map(writer, func(entry *ilcd.ZipFile) (string, []byte) {
  if entry.Type() == ilcd.FlowDataSet {
    data, err := entry.Read()
    check(err)
    return entry.Path(), data
  }
  return "", nil // ignore other data sets
})

check(reader.Close())
check(writer.Close())
