AbiWord vs DOCX: Lightweight Open XML vs Microsoft Word
Technical comparison between AbiWord (.abw) and Microsoft Word Open XML (.docx). Compare single-file XML architecture against zipped Open Packaging Conventions.
AbiWord (.abw) and Microsoft Word (.docx) take radically different approaches to XML document storage. AbiWord uses a single readable XML file encompassing Dublin Core metadata, styled spans, and base64 images, whereas DOCX packages dozens of XML parts inside a zipped OPC container.
| FEATURE | ABIWORD (.ABW) | MICROSOFT WORD (.DOCX) |
|---|---|---|
| Container Format | Single XML file (or GZIP .zabw) | ZIP archive (Open Packaging Conventions) |
| Primary Specification | AbiWord AWML DTD | ECMA-376 / ISO/IEC 29500 (OOXML) |
| Metadata Standard | Dublin Core (<m key="dc.*">) | Dublin Core + Extended + Custom app.xml |
| Image Storage | Inlined base64 (<image data="...">) | Separate image binaries in word/media/ |
| Table Model | Simple 2D grid (<cell x="..." y="...">) | Hierarchical (<w:tbl>, <w:tr>, <w:tc>) |
