I was asked to create metadata (INSPIRE) for one gdataset extracted from Open Street Map. I downloaded the polygon layer and added basic information but I don't know where to find more information than this : http://openstreetmapdata.com/data/land-polygons
I have been looking for 2 hours now and I think I will go crazy soon.
So if anyone knows, thank you a lot.
Cheers,
I am especially looking about data quality !
You will not find complete metadata information about the polygon file you downloaded.
The source where you downloaded the OSM data unfortunately does not have any id associated with the polygons. If you download the data for example from Geofabrik the data will have an id associated. This way you can look up the individual lines and might get further information about the way they were created or the author.
Inspire Metadata are in XML format. You probably have to create that from scratch. There are no OSM XML metadata available as far as I know.

Hope you're doing well.
I am a developer and have a query regarding my 3d model preview on opensea testnet.
I have created a metadata file https://pattirose.growwithsabrina.org/nft/1.json
using pinanta server for hosting the glb file. Opensea failed to fetch the model for preview.
Alternatively i have tried hosting the glb file on personal hosting and used the "animation_url" key in json file but that also did not work.
All the test transactions are done on rinkeby testnet.
Please guide on how to resolve this issue, really appreciate your support.
Thanks
This doesn't answer OP question about glb files please check out comments.
The problem seems not to be with opensea. Although opensea testnet sometimes does take time fetching your image from metadata but in your case its different.
The animation_url in your metadata should actually render the 3d model, animation or whatever it is.
https://pattirose.growwithsabrina.org/nft/1.json
The animation_url in above metadata link you provided does not render anything.
You may try re uploading it to Pinata and mint again or using Areware.org instead of Pinata if it does not work for you.
Here is a sample metadata uri, you can check that if you redirect to animation_url provided in the metadata it does render the clip in browser
Could someone please guide me on how to extract a .docx file and load it onto a database using an ETL(Extract-Transform-Load) or ELT(Extract-Load-Transform) tool?
Assuming that the .docx file contains mostly unstructured data, isn't it an ELT tool I should go for instead of ETL?
The ETL and ELT tools I found this far didn't support the MS Word component. What other way is there to extract and store the content in a .docx file onto a database?
My requirement is to:
Extract the data inside the .docx file,
Convert them into meaningful data, and
Store them onto a data lake so I can perform data analysis, and take productive decisions based on those results.
It's just like how e-commerce companies convert customer reviews into meaningful data so they can take decisions to boost their sales. In my case, it's Word files I need to analyze.
I'm asking this because I've searched for so many ETL and ELT tools but couldn't find anything that supported Word files. Maybe it's because I haven't been searching for the right tool or the right way to do it?
If somebody knows a way, please guide me through the process. What should I start looking for? A tool, or a way to code the entire thing?
I've been looking for an answer for weeks now but didn't find a helpful answer. And it's starting to get really frustrating to see all the tools supporting every other component like social media, MongoDB, or whatever EXCEPT Word files.
You have to do this in 2 steps:
Extract the data from the .docx file to txt or xml
Now use SSIS to import. (Azure Data Factory if you are in the cloud)
Salesforce has two different UIs and in accordance with it, it has the possibility to store attached files differently.
Two files were uploaded via the classic UI and they are marked as 'attachments'. Other files were uploaded through the new UI and they are marked as 'files'.
I want to upload all of these files using REST API. I cannot find the proper documentation. Can somebody help me with this?
That's not 100% true. In SF Classic UI you were able to upload Files too. It's "just" about knowing the right API name of the table and you'll find lots of examples online.
Attachment and Document objects have exactly same API names, you can view their definitions in SOAP API definition or in REST API explorer (there was something which you can still see in screenshot in here, seems to be down now, maybe they're moving it to another area in documentation...)
The Files (incl. "Chatter Files") are stored in ContentDocument and ContentVersion object. The name is unexpected because long time ago SF purchased another company's product and it was called "Salesforce Content". In beginning it was bit of mess, now it's better integrated into whole platform but still some things lurk like File folders can be called Libraries sometimes in documentation but actual API name is ContentWorkspace. The entity relationship diagram can help a bit: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_erd_content.htm
ContentDocument is a header to which many places in SF link (imagine file wasting space on disk only once but being cross-linked from multiple records). It can have at least 1 version and if you need to update the document - you'd upload new version but all links in org wouldn't change, they'd still link to header.
So, how to use it?
REST API guide: https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_sobject_insert_update_blob.htm
or maybe Chatter API guide (you tagged it with chatter so chances are you already use it): https://developer.salesforce.com/docs/atlas.en-us.chatterapi.meta/chatterapi/connect_resources_files.htm
some of my answers here might help (shameless plug). They're about upload and reading data too and one is even about data loader... but you might experiment with exporting files first, get familiar with structure before you load?

I have a Word document(some template format) where it containing some placeholders for the data to be filled in and there are several Word documents like this which lies in some directory. When data comes I will be choosing different templates (based on some criteria) and fill the data and the documents have to be converted to PDF format.
I have been investigating Apache POI for this. If anyone has a good suggestion, it would be much appreciated.
As mbeckish mentioned you should indicate how you are going to run/automate this. For example is it one-off, run by hand or part of another program (and if so what programming languages do you use)?
If you are trying to automate it JODReports and Docmosis are tools that can use templates like you require and can produce PDF. JODReports is free. Docmosis is not but has several APIs. Please note I work for the company that develops Docmosis.
Hope that helps.
I've just uploaded this presentation, which presents three approaches for doing this.
Why not use any of existing PDF virtual printers?
I’ve looked through the posts on the Cloudmade site here and I get some of it, but not all. I've posted the question below, but haven't had the help I need, so I thought I'd ask the question here.
I can see that I need to:
download the tiles for the required area to my Mac (but can’t see how to do this)
convert these to a sqlite database using the map2sqlite utility, changing the code to output the tiles to a table called “ZCACHE”, not “tiles”
Copy the DB to the Application Bundle
insert some code to copy this DB on first run, from the Application Bundle to the Documents Directory
Somehow get App to use this DB and not an online one – I can’t see how that’s done.
Any help would be warmly welcomed,
Chris.
The best solution for me to have iPhone offline maps is:
1.- Generate your own maps with TileMill and then export to MBTiles format.
2.- Get the mbtiles-ios-example and use the MBTiles file you just generated. In order to compile it, you need to download Route-Me and add it to the project.
Now, there is another option (not for free): Mapbox.
