SEAD's restful service api (see http://sead.ncsa.illinois.edu/sead-acr-api ) allows you to read/write/annotate/tag/delete datasets and collections (among other things). These services are used within SEAD's bulk upload/sync command line tool and can be called from Curl or your own code to allow your application to read/write directly to/from ACR spaces.
SEAD's google id for devices is in a file called sead-google.json which is available upon request.
The SEAD Uploader is a command line tool that can be used to upload or sync portions of your disk with an ACR project space. (The upload speed you achieve will depend on your disk and network speed, but the client itself can manage >100K file uploads and we've seen at least 250MB/minute transfer speeds over a mix of large and small files.). Note: The first time you use the SEADUploader on a machine, it will run through an authentication process with Google (see below).
Steps to get started:
- Please make sure you have JAVA installed on your computer. If you don't, you can download it here: https://java.com/en/download/
- Download the SEAD Uploader jar file : sead2.0.12.jar.
- For SEAD 1.5 only, request the sead-google.json file by sending an email to SEADdatanet@umich.edu.
- On your computer, open the root directory that contains files and folders you would like to upload to your Project Space in SEAD.
- Put the sead1.2e.jar file and (for 1.5) sead-google.json files in this directory.
- Holding the SHIFT button, right click on your mouse to open a menu. Select the "Open Command Window Here" option.
- Once you have the Command Window open, invoke the SEADUploader by typing the following in the Command Window:
java -cp sead2.0.12.jar org.sead.acr.client.SEADUploader <-listonly> <-merge> <-limit<X>> <-ex<Y>> <serverUrl> <directories/files list...>
-listonly: write information about what would/would not be transferred without doing any upload
-merge: do not create new collections or datasets if ones uploaded from the same path already exist
-limit<X>: limit this run to at most X dataset uploads (any required collections will be automatically created)
-ex<Y>: exclude any file that matches the provided regular expression pattern, e.g. -ex^\..* (exlude files that start with a period) -ex*.txt (exclude all files ending in .txt). Multiple repeats of this flag can be used to exclude based on multiple patterns.
serverUrl: the base URL of the ACR project space you're interacting with, e.g. http://sead-demo.ncsa.illinois.edu/acr
directories/files lists - a list of one or more directory or file names the Uploader should work on. The Uploader will recurse (depth first) through the files and subdirectories contained within any listed directory.
-sead2: tells the Uploader to use the SEAD 2.0 API which is required to upload to https://sead2.ncsa.illinois.edu
-verify: adding this flag will cause the uploader to use a cryptographic hash to verify that the local file and the copy in SEAD are exactly the same, byte-for-byte. With SEAD 2.0, this flag should be used on a second run of the Uploader - hashes in 2.0 are calculated asynchronously and may not be available immediately after a file is uploaded.
Note: SEAD recommends always using the -merge flag unless you want duplicate file copies in SEAD for some purpose.
2.0 examples: use of the Uploader creates one Dataset with Folders and Files inside
java -cp sead2.0.12.jar org.sead.acr.client.SEADUploader -listonly -merge -sead2 https://sead2.ncsa.illinois.edu mydir
Using SEAD's 2.0 instance, check ./mydir and list the Dataset and all Folders and Files that would be created without the -listonly flag
java -cp sead2.0.12.jar org.sead.acr.client.SEADUploader -merge -sead2 https://sead2.ncsa.illinois.edu mydir
Using SEAD's 2.0 instance, create a 'mydir' Dataset in your account on sead2.ncsa.illinois.edu and create Folders and Files for all contained items. Each File will be annotated with metadata indicating the original path (user metadata: "instanceOf (http://purl.org/vocab/frbr/core#embodimentOf) with the value /mydir for the mydir directory in this example and /mydir/<relative path> for all Files). Note that if this command is run without the -merge flag, it will create a new Dataset and upload all folders and files again, even if a Dataset already exists from a prior run (which is not usually what you'd want). -merge makes the Uploader check for an existing Dataset and only uploads missing content, or folders/files added to your local directory since the last upload.
java -cp sead2.0.12.jar org.sead.acr.client.SEADUploader -merge -sead2 -limit100 https://sead2.ncsa.illinois.edu mydir
Using SEAD's 2.0 instance, locate/create a 'mydir' Dataset in your account on sead2.ncsa.illinois.edu and create Folders and Files for the first 100 contained items. Running the command again will add the next 100 items (becasue of the -merge flag it will find/skip the ones already uploaded).
java -cp sead2.0.12.jar org.sead.acr.client.SEADUploader -merge -sead2 -verify https://sead2.ncsa.illinois.edu mydir
Using SEAD's 2.0 instance, verify that all files previously uploaded to SEAD 2 are exactly the same as those on your disk. Since SEAD 2 currently calculates hash values with a delay, the -verify flag should be added on a second run of the Uploader.
SEAD 2.0 Authentication Process
Uploading data to SEAD 2.0 requires a local SEAD username/password (Social logins not yet supported). Each time you run the Uploader, you will be prompted for your username and password. Your password will be transmitted via https to the SEAD2 server, but no copy is stored on your local machine.
If you experience problems with using the SEADUploader, please contact SEAD at SEADdatanet@umich.edu and we will be happy to walk you through the steps.
