Hi there,

I am importing data from our old system to Dgraph. Since we have already used an unique identifier for an object, I would like to use this as UID.

this is how the triples look like:

\<EA78B173-0A22-47A1-B5F9-F0C0D2B369FB\> \<creator\> \<user103\> .

\<EA78B173-0A22-47A1-B5F9-F0C0D2B369FB\> \<owner\> \<user103\>

I used bulk loader and loaded the data with success. But when I query uid , it is “0x3311bb1” instead of “EA78B173-0A22-47A1-B5F9-F0C0D2B369FB”. What should I do?

Add a string to hold that ID. e.g.

```auto
<EA78B173-0A22-47A1-B5F9-F0C0D2B369FB> <creator> <user103> .

<EA78B173-0A22-47A1-B5F9-F0C0D2B369FB> <owner> <user> .
<EA78B173-0A22-47A1-B5F9-F0C0D2B369FB> <CustomID> "EA78B173-0A22-47A1-B5F9-F0C0D2B369FB" .

```

Add an index to CustomID and search for it.

No, Dgraph’s UIDs are different from yours. You’re using **UUID**.
