MainModel

PlaceDao

@Dao

    fun getPlaces(): DataSource.Factory<Int, MainModel>
	
	@Insert(onConflict = OnConflictStrategy.REPLACE)
    fun insertAll( places: PagedList<MainModel>)
	
}

PlaceViewModel

var properties: LiveData<PagedList<com.trashmaster.muellmister.network.Place>>
≠ 
properties = videosRepository.data


// New for merged ViewModel:
videosRepository.bufferPlaces(_properties.value!!)
properties = videosRepository.data

Repository

class PlaceRepository(private val database: AppDatabase) {

        withContext(Dispatchers.IO) {
            database.placeDao().insertAll(list)
