Hi @langchain4j can you please assign this issue to me if some hasn't picked this already ?

[lucifer-Hell]

Hi @langchain4j , i have started working on integration . Is it okay if i follow AzureOpenAIEmbeddingModel as standard ref for building ?

[langchain4j]

Hey, Azure uses official SDK. I guess for Jina we will have to make our own client. Please take a look here:https://github.com/langchain4j/langchain4j/blob/main/CONTRIBUTING.md#guidelines-on-adding-a-new-embedding-store-integration

[lucifer-Hell]

Yes for jina ai currently python and javascript sdks are there only . So we have to build our own client . Thanks for sharing the guidelines i hv gone through that but the standard examples mentioned anthropic and chroma doesn't have any implementation of embedding model. I hv understanding but i just wanted to confirm if we hv to follow any standard ref/example for implementing Embedding Models .

[langchain4j]

Pardon, I mixed up embedding model and store :D
For EmbeddingModel implementation example, please check NomicEmbeddingModel

Thanks for sharing we can add this point in contribute guideline doc also.
