Workshop held at Open Repository 2018, Bozeman, Montana
As of late 2016, a DSpace 7 UI Working Group has begun developing an Angular User Interface which will replace the existing UIs in DSpace 7. This effort also includes the development of a new REST API for DSpace, designed to follow the principles of a RESTful webservice and adopt emerging standards and formats. The goals of the REST API are twofold: (1) to fully support the new Angular UI, and (2) to provide a rich, RESTful integration point for third-party services and tools.
This workshop will allow developers to become more familiar with the new REST API framework before DSpace 7 is released.
This hands-on developers workshop will provide attendees with an overview of the DSpace 7 REST framework:
- standards / best practices that the API is based on (HAL, JSON+PATCH, JWT)
- DSpace 7 REST Contract (documentation of all endpoints)
- interacting with the REST API (via HAL browser, curl and/or postman)
- how to build new endpoints into the REST API
- where to look when issues arise
- how to document and test existing/new endpoints
Attendees will be expected to setup a virtual machine (or install the DSpace 7 codebase locally) to get more familiar with the codebase/development tools.
JAX-RS. Developing RESTful APIs with JavaJerry Kurian
The presentation discusses the basic REST principles and how to define a RESTful API.
The presentation then looks at the various facilities provided by JAX-RS for developing REST API using Java.
All the supported annotations and its usage are discussed with example
The rising complexity and cost of managing legacy travel distribution systems are leading many travel companies today to adopt a REST (REpresentational State Transfer) architectural style because it provides standardized resources that enable precise interaction with other REST systems. The panelists will discuss the fundamental shift in application design required to begin thinking in terms of resources rather than objects and methods and how the OpenTravel 2.0 specification is being designed to provide a common XML resource model for the travel industry.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

2. Representational State Transfer (REST) is an architectural style that
defines a set of constraints to be used for creating web services. REST
API is a way of accessing web services in a simple and flexible way
without having any processing.
REST technology is generally preferred to the more robust Simple Object
Access Protocol (SOAP) technology because REST uses less bandwidth,
simple and flexible making it more suitable for internet usage. It’s used to
fetch or give some information from a web service. All communication
done via REST API uses only HTTP request.
3. Working: A request is sent from client to server in the form of a web
URL as HTTP GET or POST or PUT or DELETE request. After that, a
response comes back from the server in the form of a resource which
can be anything like HTML, XML, Image, or JSON. But now JSON is
the most popular format being used in Web Services.
4. In HTTP there are five methods that are commonly used in a REST-based
Architecture i.e., POST, GET, PUT, PATCH, and DELETE. These correspond to
create, read, update, and delete (or CRUD) operations respectively. There are other
methods which are less frequently used like OPTIONS and HEAD.
•GET: The HTTP GET method is used to read (or retrieve) a representation of
a resource. In the safe path, GET returns a representation in XML or JSON and
an HTTP response code of 200 (OK). In an error case, it most often returns a
404 (NOT FOUND) or 400 (BAD REQUEST).
•POST: The POST verb is most often utilized to create new resources. In
particular, it’s used to create subordinate resources. That is, subordinate to
some other (e.g. parent) resource. On successful creation, return HTTP status
201, returning a Location header with a link to the newly-created resource with
the 201 HTTP status.
NOTE: POST is neither safe nor idempotent.
5. •PUT: It is used for updating the capabilities. However, PUT can also be used
to create a resource in the case where the resource ID is chosen by the client
instead of by the server. In other words, if the PUT is to a URI that contains the
value of a non-existent resource ID. On successful update, return 200 (or 204 if
not returning any content in the body) from a PUT. If using PUT for create,
return HTTP status 201 on successful creation. PUT is not safe operation but it’s
idempotent.
•
•PATCH: It is used to modify capabilities. The PATCH request only needs to
contain the changes to the resource, not the complete resource. This resembles
PUT, but the body contains a set of instructions describing how a resource
currently residing on the server should be modified to produce a new version.
This means that the PATCH body should not just be a modified part of the
resource, but in some kind of patch language like JSON Patch or XML Patch.
PATCH is neither safe nor idempotent.
6. DELETE: It is used to delete a resource identified by a URI. On successful
deletion, return HTTP status 200 (OK) along with a response body.
Idempotence: An idempotent HTTP method is a HTTP method that can be
called many times without different outcomes. It would not matter if the method
is called only once, or ten times over. The result should be the same. Again, this
only applies to the result, not the resource itself.
Example:
a=4; //idempotence
a++;//not idempotence
7. Request and Response
Now we will see how request and response work for different HTTP methods.
Let’s assume we have an API(https://www.geeksforgeeks.org/api/students) for
all students data of gfg.
• GET: Request for all Students.
• POST: Request for Posting/Creating/Inserting Data
Request
GET:/api/student
s
Request
POST:/api/studen
ts
{“name”:”Raj”}
8. •PUT or PATCH: Request for Updating Data at id=1
Request
PUT or
PATCH:/api/students/1
{“name”:”Raj”}
•DELETE: Request for Deleting Data of id=1
Request
DELETE:/api/students/1
