what is metadata package??i successfully upload image target onto cloud database, but i dont know what is metadata package??where can i found it?
Whatever metadata you
Whatever metadata you associate with your target will be returned with its search result. The metadata package is restricted to 150KB or 200KB if provided as a base64 encoding. See: https://developer.vuforia.com/resources/dev-guide/managing-targets-cloud-database-using-developer-api
Which SDK are you using?
I am using unity vuforia 2-0-18, so you mean metadata package is something similar to unique id of one image? and i can input any number i want as long as it refer to base64 encoding?
another question, i have an access and secret key you gave me with unity vuforia 2-0-18, but today i build a cloud database via vuforia target manager ( i am surprised with new feature here ), but the access and secret key i got here is different..which one should i use???
The metadata doesn't need to
The metadata doesn't need to be exclusive to a single target - multiple targets can be assigned the same metadata. And yes, you can custom define your metadata. The intention is for the metadata to enable you to associate a search result with both a target and custom defined data about that target.
You should use the new keys, we have migrated your project to our Production platform. And it will be a good idea to use the newest SDK release. There are fixes and other improvements in the current release.
