Semantic Publishing
enhances the meaning of publications by enriching them with metadata
![Page 12: iLastic: Linked Data Generation Workflow and User Interface for iMinds Scholarly Data](https://reader031.vdocuments.us/reader031/viewer/2022030318/5a6ea8907f8b9a9b2a8b4b59/html5/thumbnails/12.jpg)
Semantic Publishing: ad-hoc solutions
different agents ownoverlapping or complementary scholarly data
use their own ad-hoc solutionsto generate and publish their own Linked (Open) Data
![Page 13: iLastic: Linked Data Generation Workflow and User Interface for iMinds Scholarly Data](https://reader031.vdocuments.us/reader031/viewer/2022030318/5a6ea8907f8b9a9b2a8b4b59/html5/thumbnails/13.jpg)
Semantic Publishing: fragmented datasets
different agents ownoverlapping or complementary scholarly data
focus on metadata or content, rarely on both
content annotations are rarely published as datasets
