+#### Add a visual cue about the loading of a .data file
+
+The .data files are crucial for the recognition of certain types of text. For example, to read the MRZ zone on passports, the file MRZ.data must be loaded first. These .data files are loaded from the server on demand at runtime. At present, these files are quite large, for example, MRZ.data is about 10MB. Although these files are cached locally as soon as they are downloaded, loading them for the first time can be quite time-consuming. To make the process user-friendly, it's recommended to show a visual cue about the loading process to the user with the help of the APIs `onResourcesLoadStarted`, `onResourcesLoadProgress` and `onResourcesLoaded` :
+
+```js
+Dynamsoft.DLR.LabelRecognizer.onResourcesLoadStarted = (resourcePath) => {
+    console.log("Loading " + resourcePath);
+    // Show a visual cue that a model file is being 
+}
+Dynamsoft.DLR.LabelRecognizer.onResourcesLoadProgress = (resourcePath, progress) => {
+    console.log(resourcePath + "loading progress: " + progress.loaded + "/" + progress.total);

+}
+Dynamsoft.DLR.LabelRecognizer.onResourcesLoaded = (resourcePath) => {
