Line 1: =General/Broader Discussion of Rosetta Task Categorization - beyond Unicon Contributors= ~~=Analysis of Tasks Icon/Unicon Unimplemented=~~ While the primary goal of this page was to help Unicon (and Icon/ObjectIcon) contributors, a secondary goal is to encourage a general discussion of task classification/sub-classification. (I know that SML may have a huge impact on this once an approach is found). ~~The following summarizes tasks that are not completed for Icon/Unicon on Rosetta Code. Note: This is not dynamically compiled and tasks may have been completed.~~ Please feel free to add comments and discussions here. ~~My intent is twofold.~~ * Encourage more contribution from other by more clearly identifying areas where they can help. =Analysis of Tasks Icon/Unicon Unimplemented= * Encourage a general discussion (beyond Icon/Unicon) of task classification/sub-classification. (I know that SML may have a huge impact on this once an approach is found). The following summarizes tasks that are not completed for Icon/Unicon on Rosetta Code. The primary intent here is to encourage more contribution from other by more clearly identifying areas where they can help. While I realize that some of the tasks could easily fall into multiple categories, I've tried to pick a (near) best fit.
