Dear Elenae,
Don't think there is an option in Adobe Analytics Standard to extract (Complete Dump at one go)the different Attribution Models other than Workspace since it was a feature within Workspace.
You can use Adhoc Analysis to extract 50K Rows in one go, but attribution models available in Adhoc Analysis are Last Touch, First Touch, Linear and Participation.
Even Data Warehouse has Participation Metric, but i don't think it can accommodate other Attribution Models.
So, I can think of two solutions,
1. API 2.0: Adobe Analytics API 2.0 and Workspace work on the same platform, so it might help (Sorry i don't have much knowledge on APIs and its limitations, you can check out).
2. Workbench: Adobe Analytics Premium feature should have.
Thank You!
