Hi, Holger, thank you, I will try your suggestion. However, I use MongoDB 3.4, and I think that Voyage has support for only versions under 3.0. Am I right? Stef, collection in mongo is a container for documents. For example, here three documents are inserted in collection "inventory": db.inventory.insertMany([ { item: "journal", qty: 25, tags: ["blank", "red"], size: { h: 14, w: 21, uom: "cm" } }, { item: "mat", qty: 85, tags: ["gray"], size: { h: 27.9, w: 35.5, uom: "cm" } }, { item: "mousepad", qty: 25, tags: ["gel", "blue"], size: { h: 19, w: 22.85, uom: "cm" } } ]) https://docs.mongodb.com/manual/tutorial/insert-documents/ Mark 2017-04-30 10:37 GMT+02:00 Stephane Ducasse <stepharo.self@gmail.com>:

Hi,
Hi!
Is it possible to retrieve data from Mongo collection if it was not created via Voyage? Meaning that I do not have a class in Pharo that would correspond to said collection (should I implement one?).
Yes. But you probably need to customize a bit.
1.) Make sure you refer to the right collection...
descriptionContainer <mongoContainer> ^VOMongoContainer new collectionName: 'yourExistingCollectionName' yourself
2.) For materialization.. you should at least have _id (okay every entry does that) VOMongoSerializer fieldVersion (#version on my old Voyage) VOMongoSerializer fieldType (#instanceOf)
and then things should work out. You can probably add #version and #instanceOf to your existing objects?
