Im using .NET Package and would like to store some extra data/metadata for each PackagePart. For now Im having a "shadow" file for each file. For myfile1.dat there is a myfile.dat.meta. In for instance SharpZipLib it is possible to add ExtraData (byte[]) for each ZipEntry but for some reasons I have choosen Package for this project. Is it possible somehow to add this functionality to (Zip)Package? I would like to be able to attach metadata to each PackagePart without using "shadow"-files. Is it possible to use ADS (Alternate Data Stream) for a ZipPackage? Any other options?

I am reading a pdf file from AWS s3 bucket and want to generate a new file with additional custom metadata using node in lambda.
I tried with pdf-lib NPM and was able to generate a new file but didn't find a way to add custom metadata. the NPM document only has methods to add default properties like title, author.
Please suggest any way to add custom metadata
the best library for PDF manipulation is pdfmake
https://www.npmjs.com/package/pdfmake
you can achieve any thing from using this library.
In my application, I need to send templated HTML emails from an Azure Function.
The content is fairly large and getting the HTML to work in all clients can be pretty hard, even with the help of something like https://litmus.com/pre-send-testing. For this reason, I do not want to to use string concatenation/interpolation. I want to have the email content in a file I can view/edit in an IDE.
I need to replace some content with text for the specific recipient.
Ideally, I would like to have conditional logic in the template to avoid too much duplication (although this is not essential).
I have used the excellent https://github.com/toddams/RazorLight nuget package in other environments but unfortunately it does not work in Azure Fucntions.
Are there any other solutions for text templating for HTML that work in Azure Functions?
At the moment my best option is something like this (where Body.html is an embedded resource file):
StringBuilder body = new StringBuilder();
Stream template = this.GetType().Assembly.GetManifestResourceStream("EmailTemplating.Body.html");
using var reader = new StreamReader(template, Encoding.UTF8);
body.Append(reader.ReadToEnd());
body.Replace("{{recipient-name}}", "Jim");
In the end, we used https://github.com/rexm/Handlebars.Net which has good templating features (standard Moustache/Handlebars functionality) and worked a charm in Azure Functions.
Did you consider storage for the purpose? You can store a template file say template.html in a blob container and leverage it whenever required (download the file into a MemoryStream and make the Stream the content of the Function’s response/ the content for the next action based on your reqirement.
I'm trying to use Dropbox as a cloud-based file receptacle for an app/script. The script, written in Python, needs to take PDFs from the Dropbox and use the tika-python wrapper to convert to string.
I'm able to connect to the Dropbox API and use the files_download_to_file() method to download the PDFs to disk, and then use the tika from_file() method to pull that download file from the disk to process. Example:
# Download ex.pdf to local disk
dbx.files_download_to_file('/my_local_path/ex_on_disk.pdf', '/my_dropbox_path/ex.pdf')
from tika import parser
parsed = parser.from_file('ex_on_disk.pdf')
The problem is that I'm planning on running this app on something like Heroku. I don't think I'm able to save anything locally and then access it again. I'm not sure how to get something from the Dropbox API that can be directly referenced by the tika wrapper to run the same as above. I think the PHP SDK has a file_get_contents and a file_put_contents set of methods but it doesn't appear to have a companion in the Python SDK.
I've tried using the shareable links in place of a filename but that hasn't worked. Any ideas? I know there's also the files_download method which downloads the FileMetadata object but I have no idea what to do with this and am having trouble finding more about it.
TLDR; How can I reference a file on Dropbox with a filename string such as 'example.pdf' to be used in another function that is trying to read a file from disk, without saving that Dropbox file to disk?
I figured it out. I used the files_download method to get the byte string and then use the from_buffer method of tika instead:
md, response = dbx.files_download(path)
file_contents = response.content
parsed = parser.from_buffer(file_contents)
I had read that the Azure Search .NET SDK uses NewtonSoft.Json to convert it's models to/from json in it's underlying REST API calls so I've been doing the same in my own app.
I have a simple app which creates a new Index using the .NET SDK. To do this, I was defining my Index in a json file, using the format outlined here https://learn.microsoft.com/en-us/rest/api/searchservice/create-index and then I was converting this to a Microsoft.Azure.Search.Models.Index object using Newtonsoft.
var index = JsonConvert.DeserializeObject<Microsoft.Azure.Search.Models.Index>(System.IO.File.ReadAllText("config.json");
This was working fine before I configured custom Analyzers, but now that I have custom Analyzers in my config, the Analyzers, Tokenizers, and TokenFilters are not being resolved into the correct types. ie. my custom Analyzer is being deserialized as a Microsoft.Azure.Search.Models.Analyzer, instead of Microsoft.Azure.Search.Models.CustomAnalyzer, same goes for the Tokenizers and TokenFilters, they are being deserialized into the base types.
Is there an easy way I can create an Index like this in the .NET SDK from a json file?
Unfortunately this is not an officially supported scenario. While it works for simple index definitions, we're working to understand what we need to do to be able to support all cases.

In the meantime, you might be able to get it working yourself by adapting the JsonSerializerSettings initialization code at the bottom of this file.
`webClient.UploadFile("http://www.myurl.com/~/media/DCF92BB74CDA4D558EEF2D3C30216E30.ashx", #"E:\filesImage\Item.png");
I'm trying to upload images to sitecore using webclient.uploadfile() method by sending my sitecore address and the path of my local images.But I'm not able to upload it.I have to do this without any API's and Sitecore Instances.
The upload process would be the same as with any ASP.net application. However, once the file has been uploaded you need to create a media item programtically. You can do this from an actual file in the file system, or from a memory stream.
The process involves using a MediaCreator object and using its CreateFromFile method.
This blog post outlines the whole process:
Adding a file to the Sitecore Media Library programatically
If you're thinking simply about optimizing your developer workflow you could use the Sitecore PowerShell Extensions using the Remoting API as described in this this blog post
If you want to use web service way than you can use number of ways which are as follows:
a) Sitecore Rocks WebService (If you are allowed to install that or it is already available).
b) Sitecore Razl Service(It is third party which need license).
c) Sitecore Powershell Remoting (This needs Sitecore PowerShell extensions to be installed on Sitecore Server).
d) You can also use Sitecore Service which you can find under sitecore\shell\WebService\Service.asmx (But this is legacy of new SitecoreItemWebAPI)
e) Last is my enhanced SitecoreItemWebAPI (This also need SitecoreItemWebApi 1.2 as a pre-requisite).
But in end except option d you need to install some or other thing in order to upload the image using HTTP, you should also know the valid credentials to use any of above stated methods.
If your customers upload the image on the website, you need to create the item in your master database. (needs access and write right on the master database) depend on your security you might consider not build it with custom code.
But using the Sitecore webforms for marketers module With out of the box file upload. Create a form with upload field and using the WFFM webservices.
If you dont want to use Sitecore API, then you can do the following:
Write a code that uploads images into this folder : [root]/upload/
You might need to create folder structure that represent how the images are stored in Sitecore, eg: your images uploaded into [root]/upload/Import/ will be stored in /sitecore/media library/Import
Sitecore will automatically upload these images into Media library
Hope this helps
Option: You can use Item Web API for it. No reference to any Sitecore dll is needed. You will only need access to the host and be able to enable the Item Web API.

I guess that is pretty much what you need, but as Jay S mentioned, if you put more details on your question helps on finding the best option to your particular case.
