Description

 

The tika DWG reader is only pulling meta data from up to drawing format AC1024  (see code snippet) where it looks to be AC1027 & AC1032 can also be read from the same get2007and2010Props meta data extractor.

 switch (version) {
            case "AC1015":
                metadata.set(Metadata.CONTENT_TYPE, TYPE.toString());
                if (skipTo2000PropertyInfoSection(stream, header)) {
                    get2000Props(stream, metadata, xhtml);
                }
                break;
            case "AC1018":
                metadata.set(Metadata.CONTENT_TYPE, TYPE.toString());
                if (skipToPropertyInfoSection(stream, header)) {
                    get2004Props(stream, metadata, xhtml);
                }
                break;
            case "AC1021":
            case "AC1024":
                metadata.set(Metadata.CONTENT_TYPE, TYPE.toString());
                if (skipToPropertyInfoSection(stream, header)) {
                    get2007and2010Props(stream, metadata, xhtml);
                }
                break;
            default:
                throw new TikaException("Unsupported AutoCAD drawing version: " + version);
        } 

Looks like the case statement just needs extending and for examples files to be created for AC1027/AC1032.
